Baby Registry Checklist: What to Actually Buy (and Skip)

The few things worth buying new, no exceptions

Most of a registry is flexible — sizes, styles, and brands genuinely come down to preference. A short list isn't: the car seat, the crib or bassinet, and the mattress that goes in it. Buy these new. A car seat with an unknown crash history, or a crib that's been recalled since it was manufactured, isn't worth the savings of going secondhand. If a friend or relative offers you a hand-me-down car seat or crib, it's fine to say a plain, warm no — most people who've researched this understand exactly why.

Safe sleep setup

• A crib, bassinet, or approved co-sleeper that meets current safety standards, bought new
• A firm mattress sized correctly for that specific crib or bassinet (no gaps around the edges)
• Fitted sheets — that's genuinely all that needs to go in the crib for the first year
• A sound machine, if you want one, kept a safe distance from the crib rather than clipped to it

Feeding

This is one of the harder categories to shop ahead of time, because you won't know your baby's preferences (nipple flow, bottle shape) until they're actually feeding. Register for a small starter set rather than a full case of one bottle brand, and expect to adjust once your baby's had a chance to try a few. Our comparison of baby bottles breaks down flow rates and shapes if you're picking a starting point, and once solids start, our guide to starting solid foods and our high chair comparison cover what comes next.

Bigger gear: strollers, carriers, and travel

These are worth researching before you buy rather than registering for on instinct, since they're some of the pricier items on a typical registry and the right pick depends on your specific life — an everyday stroller for city sidewalks is a different product than one built for a family that drives everywhere. Our stroller comparison and double stroller guide cover everyday and travel-system options, our convertible car seat guide covers what comes after the infant seat, and our baby carrier comparison breaks down wraps, slings, and structured carriers if you want hands-free options for the early months.

If overnight stays at a relative's house or actual travel are on the horizon, our guide to pack 'n plays and travel cribs and our diaper bag comparison are worth a look before you're packing for a trip at the last minute.

Buying the car seat new is only half the safety picture — knowing how to read its expiration date and what that date actually protects against matters just as much a few years in. Our guide to car seat expiration dates covers where to find it and when a hand-me-down seat is genuinely fine versus a hard no.

A swing or bouncer is one of the bigger judgment calls on a registry, since plenty of babies never need the pricier motorized option. Our comparison of baby swings and bouncers breaks down what a swing does that a bouncer can't, and which one to register for first.

Clothing: less than you'd think

Newborn-size clothing gets outgrown fast — often within a few weeks — so a full wardrobe in that size is one of the most common overspends on a registry. A better approach is a handful of newborn-size basics (onesies, a couple of sleepers) and a heavier concentration of 0–3 and 3–6 month sizes, since your baby will live in those longer. Growth is unpredictable enough that it's worth waiting on a lot of specific-size clothing until closer to when your baby will actually wear it. Basic cotton bodysuits are the one category worth registering for in real bulk rather than a few pieces — our comparison of bodysuit multipacks covers which pack sizes and sleeve lengths actually get used daily versus which sit in a drawer.

Diapering and health basics

• Diapers in newborn and size 1 — but not a huge stockpile in one size, since newborns move through sizes quickly
• Wipes, a changing pad, and diaper rash cream
• A digital thermometer and infant pain/fever reliever appropriate for newborns (confirm dosing with your pediatrician before you need it at 2 a.m.)
• A diaper pail, if you want a dedicated one rather than a regular lidded trash can

Whatever cream ends up in the diaper bag, most everyday redness clears with more frequent changes and a thick barrier layer. Our diaper rash guide covers how to tell ordinary irritation apart from a yeast rash that needs an antifungal instead of more of the same cream.

What to skip or hold off on

• Wearable blankets and sleep sacks in every size at once — babies grow out of them fast; buy the current size as you go.
• A large stock of one specific formula before you know your baby will tolerate it well.
• Baby shoes for a newborn who isn't walking — they're mostly decorative at this stage.
• Bottle warmers and sterilizers as must-haves — genuinely useful for some families, skippable for others; wait until you know your routine.

If you're still working through the rest of the pre-baby list, our hospital bag checklist covers what to have ready for delivery itself, and our guide to choosing a pediatrician covers the one big decision that isn't about gear at all.

Sleepwear is a category worth understanding rather than just guessing on, since children's pajamas fall under a federal flammability standard most parents never see explained. Our breakdown of snug-fit vs. flame-retardant pajamas covers what the label on the tag actually means before you register for or buy any.

Once your baby's grown into toddlerhood and the bodysuit-heavy wardrobe stops making sense, our roundup of Amazon Essentials toddler clothing multipacks covers the leggings, joggers, and tee multipacks that replace it — useful to bookmark now even though it's a later-stage purchase.
