The Infant Years (Ages 0-2): Your Baby’s Financial Setup, Step by Step

Your baby won’t remember a thing about money from the first two years, and almost all of the work in this stage falls to you. It may still be the most valuable money work you ever do for them. The Social Security number you apply for at the hospital, the accounts you open, and the automatic deposit you set up this year all have a longer runway than anything you’ll do for your child later. At a hypothetical 7% average annual return, the model used throughout GoodNest’s guides, $100 a month from birth could grow to about $42,100 by age 18. Start the same deposits on your child’s third birthday instead, and you’d have about $31,100, roughly $11,000 less, even though you’d have skipped only $3,600 in deposits.

This guide is the first stage of The Age-By-Age Playbook to Financial Literacy. It walks through the first two years in the order the work tends to come up: the paperwork that unlocks everything else, the protection your family needs before it invests, the free money available to babies born now, where the savings should live, and how to automate them so they keep growing through the busiest years of your life. It ends with the first money habits a baby or toddler can actually pick up.

Why the first two years matter most

Two jobs define this stage. The first is building a foundation: the documents, insurance, and legal paperwork that keep your family steady if something goes wrong. The second is starting the clock. A newborn has about 18 years before college, more time than any later starting point allows, and compounding rewards time above everything else, as How Does Compound Interest Actually Work for Minors? explains.

Here’s what that means in practice. At the same hypothetical 7% return, $1,200 deposited over your baby’s first year, $100 a month, could be worth about $3,900 by 18. The same $1,200 deposited the year your child turns 17 would be worth about $1,240. Markets never move in a straight line, so real results will be lumpier, but the direction holds: the earlier a dollar goes in, the longer it has to grow. The Cost of Waiting runs the numbers for longer delays.

The catch is that this stage also brings new bills and less sleep, so the plan has to run without you. The rest of this guide is built that way: set things up once, automate what you can, and let time handle the rest. Here’s the order the work usually comes up.

Step 1: Get the paperwork that unlocks everything

Nearly every account and tax break in this guide depends on one number. When you fill out the birth certificate form at the hospital, you can apply for your baby’s Social Security number at the same time. The state agency that issues birth certificates then shares your baby’s information with the Social Security Administration, which mails the card to you. State processing takes about two weeks on average, and the agency says to allow two more weeks for the mail, according to its answer on how long a child’s number takes. If you wait and apply later, there may be delays while it verifies the birth certificate.

Here’s what the number unlocks:

• The child tax credit. It’s worth up to $2,200 per qualifying child. You (or your spouse, on a joint return) and your child must each have a Social Security number that’s valid for employment and issued before your return’s due date, including extensions, the IRS explains.
• A Trump Account and Treasury’s $1,000. Treasury’s automatic accounts cover eligible children with a valid Social Security number, and the $1,000 deposit requires one too. Step 3 covers both.
• Everything else. Keep the card with a certified copy of the birth certificate somewhere safe, because you’ll reach for both as you open accounts in your child’s name.

One more form deserves a look once the card arrives: your W-4. A new child can lower your tax bill, and updating your withholding lets you see that money in each paycheck instead of waiting for a refund. Finding the Funds shows how, and how to turn the difference into a monthly deposit for your baby.

Step 2: Protect your family before you invest

Investing for your baby matters less than making sure your family can absorb a shock. That’s the idea behind The “Oxygen Mask” Rule of Parental Finance: keep your own emergency savings and retirement contributions going first. In the infant years, four more protections belong on the list.

Add your baby to your health plan

Don’t let this deadline slip by in the newborn haze. If you have coverage through work, you must notify the plan within 30 days of the birth to enroll your baby under federal special enrollment rules, the Department of Labor explains. If you buy coverage through the federal Marketplace, apply within 60 days of the birth, and the coverage will start the day your baby was born, according to HealthCare.gov. You can apply for Medicaid or the Children’s Health Insurance Program at any time of year.

Write a will that names a guardian

A will is where you name the person you’d want to raise your child if you and the other parent can’t. A living trust can’t do that job, so even parents with a trust still need a will, Nolo notes. Many parents haven’t gotten there yet. In Caring.com’s 2025 wills and estate planning study, only 24% of respondents said they had a will, and adults with children under 18 made up the largest group without wills or other estate planning documents. Name a backup guardian too, and talk with both people before you put their names in writing. Understanding Trust Funds for the Middle Class explains how a trust can manage money for your child while the guardian raises them.

Check your life insurance

Life insurance replaces your income for the years your child depends on it, and many families have a gap. Cost is often a misjudgment rather than a real barrier. In the 2026 Insurance Barometer Study from LIMRA and Life Happens, 38% of U.S. adults, about 92 million people, said they needed life insurance or more of it, and roughly three in four overestimated what it costs. Adults under 31 overestimated the cost of a $250,000, 20-year term policy by about five to six times. Consider a term policy that lasts until your youngest child is grown, and get real quotes before you decide it’s out of reach.

Update beneficiaries and successors

A new baby is a good time to review the beneficiaries on your retirement accounts and life insurance. Naming a young child directly can create problems, because a minor can’t manage an inheritance; the trust guide above explains the alternatives. As you open accounts for your baby, name a successor owner for each 529 plan and a successor custodian for any custodial account, as Naming Successor Custodians explains.

Step 3: Claim the free money

Babies born now can qualify for money from Treasury, from some states, and through the tax code. Very little of it arrives without a parent claiming it.

The Trump Account and its $1,000 seed

Trump Accounts are tax-advantaged investment accounts for children under 18, created by the 2025 tax law. On October 1, 2026, Treasury announced that it had finished automatic enrollment, so every eligible child under 18 with a valid Social Security number now has a Trump Account, according to its announcement. The catch is that a parent or guardian must claim the account in the official Trump Accounts app to manage it and to let family, friends, and employers contribute. Claiming is also how an eligible child receives Treasury’s one-time $1,000 seed contribution.

For a newborn, the timing depends on when the Social Security number arrives. Treasury plans periodic enrollment rounds for children it identifies after the first rollout, and automatic accounts are invested together through a Treasury-run master trust until a parent claims them, The National News Desk reported. You don’t have to wait for a round, though. A baby qualifies for the $1,000 if they were born in 2025, 2026, 2027, or 2028, are a U.S. citizen, have been issued a Social Security number, and haven’t had an earlier election processed, according to the IRS’s summary of the proposed rules. The parent or guardian who expects to claim the baby as a qualifying child makes the election, possibly in the same year the baby is born, and Form 4547 is the IRS form for opening the account and requesting the money. How to Claim the Federal Seed Money Pilot walks through the app, your IRS online account, and the form step by step.

Claim it early. In Treasury’s historical analysis of $1,000 invested in a broad index of U.S. stocks, waiting six months after birth to invest it cost a median of $300 by age 18, according to the proposed regulations for the pilot program. At a steady 7% a year, $1,000 deposited at birth could be worth about $3,380 at 18.

Once the account is claimed, a few firm rules apply. Family and employers share a $5,000 yearly contribution limit, an employer can put in up to $2,500 of that without it counting as the employee’s taxable income, and the money generally can’t come out before January 1 of the year your child turns 18, the IRS says. The $1,000 itself doesn’t count toward the $5,000 limit, under the proposed pilot rules. Until your child turns 18, the money has to be invested in mutual funds or ETFs that track the S&P 500 or another index of mostly U.S. stocks, Accounting Today reported. The 530A Trump Account Explained covers the rest, and Navigating 530A Employer Contributions covers what to ask HR.

State programs for newborns

Some states add money of their own, usually through their 529 plans. Fifteen states offer grants to residents who use their 529 plans, Saving for College reports, and several of the newborn programs on its list close at or near the first birthday:

Other programs give families more time or need no paperwork at all. Illinois deposits $50 for children born or adopted from 2023 on when a parent claims it in a Bright Start or Bright Directions 529 account before the child’s 10th birthday, under Illinois First Steps. California’s CalKIDS opens accounts for newborns automatically, Pennsylvania’s Keystone Scholars deposits $100 for every baby born in the state, and Maine’s Alfond Grant provides $500 automatically, The College Investor reports. These programs generally work only with your own state’s 529 plan, and their rules change, so check with your state’s plan before you open an account elsewhere.

Tax breaks that can fund the deposits

Two tax breaks can free up cash in the infant years. The first is the child tax credit, worth up to $2,200 per child, with the full amount available to families with income up to $200,000, or $400,000 on a joint return, according to the IRS. Spread across a year, $2,200 works out to about $183 a month, more than enough to cover a $100 automatic deposit.

The second is a dependent care flexible spending account, if your employer offers one. The 2025 tax law raised the most you can set aside for child care before taxes from $5,000 to $7,500 a year, starting in 2026, though employers aren’t required to adopt the higher limit, Hill Ward Henderson explains. Federal rules let employer benefit plans accept mid-year changes after a birth, though they don’t require it, under Treasury regulations on cafeteria plans, so ask HR soon after your baby arrives. The same budgeting guide from Step 1 shows how to steer savings like these into your baby’s account.

Step 4: Choose where the money will live

You don’t need every account, and you don’t need to decide everything this year. Each account below does a different job, and a baby’s savings can start in one or two of them. Comparing Investment Accounts for Kids compares them in depth.

For many families, a simple start is the Trump Account for the $1,000, plus one account for their own savings: a 529 plan if the money is meant for education, or a custodial account if it should be able to cover anything that benefits your child.

A 529 plan grows tax-free when it’s spent on qualified education costs, and it rewards an early start in one more way. Unused 529 money can roll into the beneficiary’s Roth IRA, up to $35,000 over a lifetime, but only from an account that has been open at least 15 years and only from money that has been in it at least five, Saving for College explains. A 529 opened in the infant years clears that bar around your child’s 15th to 17th birthday. A parent-owned 529 also counts more lightly on the FAFSA than an account in your child’s name, as How 529s and UTMAs Impact the FAFSA explains.

A custodial account under your state’s UTMA or UGMA law can pay for anything that benefits your child, but every deposit becomes your child’s property for good, and your child takes control at an age set by state law, from 18 to 25. UTMA vs. UGMA: What’s the Difference? explains the two laws, and Custodial Brokerage Accounts vs. Parent-Owned Taxable Accounts weighs keeping the money in your own name instead.

A custodial Roth IRA will have to wait, because contributions require earned income, which most babies don’t have. The Custodial Roth IRA picks up the story when your child gets a first job.

Step 5: Automate the deposits

The best savings plan for a new parent is one that doesn’t depend on remembering. Pick an amount you could keep paying in a lean month, schedule it for the day after payday, and let it run. At a hypothetical 7% average annual return, $50 a month from birth could grow to about $21,000 by 18, and $100 a month to about $42,100. Automating the Nest Egg covers the setup in detail.

• Start small if you need to. Many 529 plans lower their minimum when you sign up for automatic contributions. Wisconsin’s Edvest plan, for example, requires $25 per contribution but drops to $15 with an automatic plan, and you can change or stop scheduled contributions at any time, Saving for College notes.
• Use payroll if it’s offered. Some employers let you send part of each paycheck straight to a 529 plan, the same source notes.
• Raise it on each birthday. A small increase every year, tied to a date you won’t forget, adds up over 18 years.
• Send windfalls the same way. Tax refunds, gift money, and bonuses can go straight to the account you’ve already chosen for them.

Invest for an 18-year runway

Money you won’t touch for 15 years or more can be invested mostly for growth. Broad, low-cost index funds keep it simple, as Index Funds vs. Stock Picking for Minors explains, and an age-based 529 portfolio shifts toward bonds and cash on its own as college approaches, the approach behind Building a Target-Date Glide Path. The GoodNest Guide to Investment Strategies & Portfolio Allocation covers how much risk fits each stage.

What a head start is worth

Automating early matters because the earliest deposits have the most time to grow. The chart shows what $100 a month could be worth at 18, at a hypothetical 7% average annual return, if you start at birth or wait one, two, or three years.

• Your deposits
• Growth

Hypothetical example: $100 deposited at the end of each month from the starting age through age 18, a 7% average annual return, earned monthly at the equivalent monthly rate, and no fees or taxes. Not a prediction or guarantee.

See the numbers

$100 a month through age 18

Start	You deposit	Value at 18
Birth	$21,600	$42,092
Age 1	$20,400	$38,181
Age 2	$19,200	$34,526
Age 3	$18,000	$31,110

Starting at birth means putting in $3,600 more than starting at age 3, and it could leave you with about $11,000 more at 18. Each year of waiting in the infant years gives up between about $3,400 and $3,900 of value at 18. Those first three years are one-sixth of the deposits in an 18-year plan, but they could grow to more than a quarter of the balance. If money is tight, automate what you can now and raise it later. Even $25 a month from birth could grow to about $10,500 by 18.

Step 6: Invite your village

Babies attract gifts, and the earliest ones have the longest runway. At a hypothetical 7% return, $500 given at a baby shower could grow to about $1,690 by 18. A few ground rules keep family gifts simple:

• Know the gift tax limit. For 2026, the annual exclusion for gifts remains $19,000 per recipient, the IRS says, so each grandparent, aunt, or friend can give your child up to that amount this year without using any of their lifetime gift tax exemption. The Impact of the 2026 Gift Tax Exclusion covers the details.
• Coordinate Trump Account gifts. The $5,000 yearly limit covers every relative, friend, and employer combined, so agree on who gives what before a birthday.
• Ask for contributions instead of more toys. Discussing Wealth with Grandparents and The GoodNest Guide to Asking for Investments Instead of Toys offer wording that keeps the request gracious.
• Match the milestone to the account. Milestone Contributions and Structuring Milestone Contributions map showers, welcome ceremonies, and first birthdays to the accounts that fit them.
• Say thank you, then show the growth. Thank You Notes and Portfolio Updates shows how to share what a gift has become.

GoodNest is built for this part of the plan. You create a page for your child and share one link with the people you choose, and the same page can stay with your child from the shower to graduation. Guests can give without creating an account, often alongside a small keepsake like a book, and the page keeps each gift with the giver’s name and note. Guests can also seal a letter, a voice note, or a video in your baby’s time capsule, kept until the age you choose. GoodNest doesn’t hold or invest the money. Gifts go straight to you by Zelle, Venmo, or PayPal, and you move each gift into the account it’s meant for, so shower money can wait with you until your baby’s accounts are open. Once they are, set the account as the destination on your child’s page, and the page tells family where their gifts go. Building Your Village covers the bigger picture.

Your baby’s first money lessons

A baby can’t learn what money is, but the skills money decisions depend on are already forming. Children aren’t born with executive function skills like working memory and self-control, but they’re born with the potential to develop them through interactions and practice, according to Harvard’s Center on the Developing Child. Its activity guide suggests games for each age, and a few translate naturally into money play:

• Copying games, from about 6 months. Babies love to imitate adults. Let your baby “help” as you put groceries away or hand over a bag at checkout, and name what you’re doing as you go.
• Simple pretend play, as a toddler. A play kitchen or a pretend store gives a toddler a way to act out shopping, paying, and waiting in line.
• Games with turns and rules, from about 18 months. Taking turns, waiting for a signal, and sorting toys by color or size all exercise the self-control and memory a saver relies on.

Keep real coins out of the game for now. Coins are a choking hazard, and the American Academy of Pediatrics advises against letting infants and young children play with them, according to HealthyChildren.org. They can wait for the preschool years, when The Early Years (Ages 3-5) picks up with counting, sorting, and savings jars.

The most important lesson in this stage is one your baby will absorb without trying: how the adults around them talk about money. Get in the habit of narrating your choices out loud, like “We’re putting your birthday money in your savings so it can grow” or “We’ll wait until payday for that.” Agree with your partner on the values you want to pass along. The Age-By-Age Playbook to Financial Literacy shows how those habits build into allowances, investing, and a first paycheck in the years ahead.

Your infant-years checklist

Before your child’s second birthday, aim to check off each of these:

• Social Security number. The card is home, stored with a certified copy of the birth certificate.
• Health coverage. Your baby was added to your plan before the deadline.
• Trump Account. It’s claimed in the official app, and the $1,000 is requested if your baby qualifies.
• State program. Any newborn 529 grant or seed deposit from your state is claimed.
• Savings account. A 529 plan or custodial account is open, with a successor named.
• Automatic deposit. A monthly transfer runs the day after payday.
• Will. It’s signed and names a guardian and a backup.
• Insurance and beneficiaries. Life coverage is in place, and every beneficiary form is current.
• Family plan. Relatives know how to give, and every gift got a thank-you.
• First-birthday raise. The monthly deposit went up, even by a little.

The bottom line

The infant years are the one stage when your child learns almost nothing about money and you can do the most for their financial future. Get the Social Security number at the hospital, protect your family with health coverage, a will, and life insurance, claim the money your baby qualifies for, and automate a monthly deposit into the accounts that fit your goals. Then let time do the work while you narrate your own money choices out loud. When your toddler is ready for coins and savings jars, the next stage of The Age-By-Age Playbook to Financial Literacy begins.

Frequently asked questions

When should I start investing for my baby?

As soon as you can, because time is the biggest advantage a newborn has. At a hypothetical 7% average annual return, $100 a month started at birth could grow to about $42,100 by age 18, while the same deposits started at age 3 could reach about $31,100. If you can’t afford much yet, automate a small amount now and raise it on each birthday.

What is the best investment account for a newborn?

There isn’t one best account, because each does a different job. If your baby is a U.S. citizen born from 2025 through 2028 with a Social Security number, claim the Trump Account to receive Treasury’s one-time $1,000. For education savings, a 529 plan offers tax-free growth for qualified expenses. A custodial account suits flexible gifts, but the money becomes your child’s to control at 18 to 25, depending on your state.

Does my baby already have a Trump Account?

Possibly. On October 1, 2026, Treasury said every eligible child under 18 with a valid Social Security number now has a Trump Account, and it plans periodic enrollment rounds for children identified later. Either way, a parent or guardian has to claim the account in the official Trump Accounts app to manage it, accept contributions from family and employers, and receive the $1,000 for eligible babies.

How much should I save for my baby each month?

Whatever you can automate without strain. At a hypothetical 7% average annual return, $50 a month from birth could grow to about $21,000 by 18, and $100 a month to about $42,100. Some 529 plans accept automatic contributions as small as $15, and you can raise the amount as your budget allows.

Can I open a Roth IRA for my baby?

Usually not. A Roth IRA requires earned income, which most babies don’t have. A Trump Account works like an IRA without that requirement, and a custodial Roth IRA becomes an option once your child earns money from a job.
