What to Buy Before Baby Arrives: A Budget Checklist That Sorts Itself

The registry checklist that came with your baby app has 140 items on it and no sense of timing. It puts the high chair — a thing you will not use for six months — next to the car seat you legally cannot leave the hospital without. So you end up buying month-six gear in month one, on a pre-baby budget, for a baby whose preferences you haven’t met yet.

Here’s the same list sorted the way it should be: buy now, buy later, and don’t buy at all until you know. Copy it, put your own prices in it, and you’ll cut a substantial chunk out of your pre-baby spend without missing anything that matters.

Buy now — the genuinely pre-birth list

These are the things you want in the house, assembled, before the due date. Everything here has one of three justifications: you need it on day one, it takes time to install or wash, or it’s the thing a hospital will ask about.

The budget bands below are planning ranges for a mix of new and secondhand — they are my own suggested planning brackets, not survey figures. Replace each with the real price of the item you’d actually buy.

Item Why it’s a buy-now Budget band
Safe sleep space (crib or bassinet + firm mattress) Needed night one; mattress must be new and fit with no gap $150–$450
Car seat — new, installed before the due date Required for discharge; installation takes a practice run $100–$350
~7 days of newborn/0–3m clothing, washed You need clean clothes on day one, not a wardrobe $60–$120
Diapers: one small pack newborn + one pack size 1 Sizes move fast; don’t stockpile $30–$50
Wipes (2 packs) $10–$20
Feeding starter: 2–3 bottles of one type, or nursing basics Test the preference before buying eight $40–$120
Breast pump (if using) — check plan coverage first Many plans cover one; sort the paperwork early $0–$200
Swaddles or sleep sacks (3–4) Laundry cycle means you need more than one $30–$70
Basic bath + health kit (tub or insert, thermometer, nail file, gas drops) You’ll want it at 2am, not on Amazon $40–$80
Changing pad + cover, and a place to put it The dresser you already own works $30–$90
1 baby carrier or wrap Frees your hands from week one $40–$150
Crib sheets (3) + mattress protectors (2) Overnight accidents need a same-night spare $30–$60
Buy-now total $560–$1,760

That’s the whole real list. Notice what’s not on it.

Buy later — real, but not yet

These are legitimate purchases at a specific later stage. Putting them on the pre-birth budget just moves money earlier for no benefit — and often locks you into a choice before you know the baby.

Item When you’ll actually need it
High chair Around 5–6 months, when solids start
Jumper / activity center Once they can hold their head up unsupported
Larger diaper sizes in bulk When they’re nearly out of the current size
6–12m clothing When 0–6m starts getting snug
Stroller (if not gifted) Useful early, but you can start with a carrier
Baby-proofing supplies When they start moving — often 7+ months
Toys beyond a couple of soft items Newborns interact with faces, not toys
Bottle sterilizer Only after you know your bottle system

Stroller is the one judgment call on this list. If you’ll be walking a lot from week one, promote it to buy-now. If you’re mostly driving and have a carrier, it can wait until you know how you actually get around with a baby.

Don’t buy — at least not in quantity, and not yet

Not because they’re bad, but because they’re preference bets you’d be placing before meeting the person with the preference.

The sorting rule you can apply to any item

When something lands on your list and you can’t decide, ask three questions in order:

  1. Will I use it in the first six weeks? No → it’s buy-later.
  2. Is it a preference the baby gets a vote on? Yes → buy one, not eight.
  3. Would I be upset if someone gifted me a different version of it? Yes → it belongs on your registry, not your cart.

That third question is the one that saves the most money, because it routes your expensive, low-preference items — car seat, monitor, carrier, pump accessories — onto the registry where someone else pays for them.

Put a real price on every line before you buy anything

The checklist is only half the job. The other half is the number, and the number only works if it’s your prices on your items minus what the registry actually covers.

That’s the trap in doing this on paper: your list changes daily, gifts arrive out of order, and by week 32 you genuinely cannot tell whether you’ve already bought a changing pad. Estimated vs. actual, item by item, is what stops you from buying things twice.

The Baby Budget & New Parent Finance Planner has a Pre-Baby Expense Planner covering nursery, gear, feeding, clothing, diapers, bath and hospital costs with an estimated and an actual column on every line — so you can build this checklist with your real prices, watch the total move as you buy, and see immediately when a category runs over. It sits next to the Registry Tracker, so an item marked “received” drops off your buy list instead of quietly staying on it.

Where this fits

Pre-baby gear is bucket one of four in the first-year budget — and, for most households, the smallest of the four. Before you optimize the crib, see the full breakdown in how much a baby costs the first year, and decide which of these items should go on your registry instead of your cart in what to put on a baby registry vs. buy yourself.

The bottom line

Sort every item by when you’ll use it and whether the baby gets a vote, and the pre-birth list collapses to about a dozen things: a safe sleep space, a new car seat, a week of clothes, a starter feeding setup, diapers and wipes in small quantities, a carrier, and a bath kit. Everything else is a month-four decision made with better information — and the expensive low-preference items belong on the registry, not the credit card.

Frequently Asked Questions

What do you actually need to buy before the baby arrives?

A far shorter list than most registries suggest: somewhere safe for the baby to sleep, a car seat that's installed before the hospital discharge, roughly a week of newborn clothing, diapers and wipes, a feeding setup, a few bath and health basics, and a way to carry the baby. Almost everything else — high chair, jumper, larger clothing sizes, most toys — is a month-four purchase you can make once you know your actual baby.

What should you not buy before the baby arrives?

Anything that depends on a preference the baby hasn't expressed yet, and anything for a stage months away. That means large quantities of one bottle type or one pacifier brand, a full wardrobe of newborn size (many babies skip it quickly), shoes, the high chair, the jumper, a wipe warmer, and a complete diaper stockpile in size 1. Buy one of the preference items and a few days' supply, then buy in bulk once you know what works.

How much should I budget for baby gear before birth?

Price the specific items you would actually buy rather than using a total from elsewhere, because the spread between secondhand-and-mid-range and all-new-premium is several times over on the same list. Build the list first, put a real price on every line, then subtract what the registry is likely to cover. Your budget number is what's left — and for most households the honest buy-now list is much smaller than the full registry.

Is it safe to buy baby gear secondhand?

Cribs, dressers, clothing, bassinets, carriers and strollers are common secondhand buys — check the model against current recall listings and make sure all original parts and hardware are present. The clear exception is the car seat: buy that new, because a used seat may have been in a crash you can't see or verify, and seats carry an expiration date stamped on the shell. Also check that any secondhand mattress is firm, flat and fits the crib with no gap.
