Baby registry checklist with quantities: what to add, and how many

In shortRegister clothes by size and with a number. For a baby born in New York City on March 15, 2027, Cotokim's list counts 61 clothing items in sizes NB to 6M and 1,432 diapers until 6 months, with balanced amounts. The list counts about 3 weeks in size NB, so most of the clothes belong in the bigger sizes.

A registry is a list other people buy from, so it works best when every line says the size and how many. The numbers on this page are Cotokim's list for one baby in New York City, born on March 15, 2027, with balanced amounts, laundry every two days, a clothes dryer and a home heated in winter. Cotokim is not a store and has no links to buy: build the list for your city and due month in the tool, then copy the quantities into the registry you use.

71 items on the list for the birth and the first 6 months, with 1,432 diapers, for the weather in New York City.

On the World Health Organization median growth curves, Cotokim's list counts about 3 weeks in size NB and 8 weeks in size 3M 1 2. Register the few NB pieces your baby will use, and ask for the rest in 3M and up. Sizes 6M and 9M meet a different season from the one your baby is born in, which is why their mix of sleeves is different. A snowsuit or bunting on the list is for going out, and it comes off for the car seat: NHTSA says bulky clothing or blankets can prevent a snug harness fit, so buckle your baby in first and then place coats or blankets over the harness 4.

Sleep, bath and diapering

  • Sleep: 1 crib, 1 crib mattress, 3 fitted crib sheets, 2 waterproof mattress covers, 2 wearable blankets, 3 swaddles, and 3 baby blankets. The baby blankets are for holding, the stroller and outings, never in the crib: it holds nothing but a fitted sheet 6.
  • Bath and hygiene: 1 baby bathtub, 2 hooded towels, 1 bottle of baby wash, and 1 nail care kit.
  • Diapering: 1,432 diapers, 3 packs of wipes, 1 tube of diaper cream, 1 portable changing pad, and 1 changing pad. Register the diapers by size: until 6 months, the list counts 348 in size N, 530 in size 1 and 554 in size 2.

Gear and the rest

  • Out and about: 1 infant car seat, 1 stroller, and 1 diaper bag.
  • Nursery: 1 room thermometer, 1 night light, 1 laundry hamper, and 1 childproofing kit.
  • Feeding: 7 burp cloths, 2 drool bibs, 1 high chair, and 2 feeding bibs. The high chair and the feeding bibs are for later, when your baby starts solid foods.
  • Health: 1 digital thermometer, 1 bottle of saline drops, and 1 oral syringe.
  • For you: 2 nursing bras, 1 box of nursing pads, 2 nursing nightgowns or pajamas, 3 packs of postpartum pads, and 4 pairs of underwear.

What to leave off the registry

  • Crib bumpers and inclined sleepers. Federal law treats them as banned hazardous products 7, and since November 12, 2022 it is unlawful to sell, make or import them in the US 8.
  • Weighted blankets and weighted swaddles. The CPSC says not to use them 6.
  • Sleep positioners. The FDA says not to use infant positioners, because they pose a risk of suffocation 9.
  • Baby neck floats. The FDA warns that their risks include death by drowning and suffocation 5.
  • Bottles, nipples and pacifiers. Cotokim does not promote them, so they are not on the suggested list. If you plan to use them, add them yourself.

The rest of what Cotokim leaves off, with the reason for each one, is on the newborn essentials checklist.

The crib holds nothing but a fitted sheet, and the safest way for a baby to sleep is flat on their back, with no pillows, blankets or toys 6. A child under age 1 should always ride in a rear-facing car seat 3. The amounts on this page are a Cotokim proposal. Checked by the Cotokim team against the sources on this page. It does not replace advice from the health care team that looks after you and your baby.

Frequently asked questions

What should I put on my baby registry?

What your baby will use, with the size and the number: clothes by size, diapers by size, the crib and its mattress and sheets, wearable blankets, the infant car seat, a stroller and the small things for bath, diapering and health. The lists above come from the same math as the tool.

How many items should a baby registry have?

There is no right total. Cotokim's list for the baby on this page has 51 entries with essential amounts, 70 with balanced amounts and 83 with complete amounts, counting each size apart.

Should I register for newborn size clothes?

For a few pieces only. Size NB lasts weeks, so the list puts most of the clothes in 3M and up, and the tool shows how many NB pieces your baby's season calls for.

Do I need everything before the baby arrives?

No. The checklist marks what is for before the birth and what can wait. The high chair, for example, is for when your baby starts solid foods.
