Planning guide

Month-by-month baby budget

Where the first-year money actually goes — by month. Use this to plan cash flow, not just totals.

Month 1

Birth, hospital bill, the gear surge

The biggest single month. Most families pay 70%+ of one-time gear, the bulk of the birth bill, plus 11+ diapers/day and any newborn formula. Plan for $3,000–$8,000 if you're on an employer plan — much higher uninsured.

Month 2

Settling in

Recurring costs dominate now: diapers, feeding, misc. Some last gear arrives (bottles, swaddles). Pediatrician copays for well-baby visits start hitting deductibles.

Month 3

Childcare prep month

Many parents start touring daycares or interviewing nannies. Registration fees, deposits, and supply fees show up. Budget $200–$1,000 in one-time childcare onboarding costs.

Month 4

Daycare often starts

A massive jump in monthly spending if paid childcare begins now. Plan for monthly tuition to be the single largest line item from this point on.

Month 5

Steady state begins

Diaper, feeding, and childcare costs become predictable. Misc costs around classes, swim, or photos may pick up.

Month 6

Solids start

Babies typically begin solids at 4–6 months. High chair, bibs, and a small grocery line item appear. Formula consumption may start to drop slightly.

Month 7

Sized-up clothes

Babies grow out of newborn and 0–3 sizes by now. Plan a small clothing refresh or rely on hand-me-downs.

Month 8

Mobile baby gear

Crawling brings new costs: outlet covers, baby gates, cabinet locks. Budget $50–$200 for childproofing.

Month 9

Mid-year doctor visits

Standard well-baby and vaccine visits continue. Sick visits become more common as immune system develops.

Month 10

Decreased formula

Babies eating more solids reduces formula or breastfeeding intensity. If on formula, expect a small monthly cost decline.

Month 11

Quiet month

Few new costs. A good time to review your registry coverage and finalize gear before the first birthday rush.

Month 12

First birthday + transition

Many families celebrate the first birthday, transition out of formula or breastfeeding, and look at toddler-tier childcare. Toddler care is usually 10–20% cheaper than infant care.

Cash flow

Three planning principles

Front-load month 1, then breathe

The first month carries the biggest hit by a wide margin: birth bills, gear, registry gaps, hospital parking, and possibly an extra week of unpaid leave. Save aggressively in late pregnancy specifically for that month. After month 1, most families settle into a predictable monthly rhythm.

Treat childcare as a separate budget line

Whether daycare starts in month 3 or month 6, it will dominate every monthly budget after that. Build it into your post-leave income plan separately — don't average it across the year.

Don't overbuy in month 0

A surprising amount of "must-have" gear can wait. Babies vary a lot, and what works for one family may not work for yours. Wait, then buy what you actually need.
