How many swaddles do I need for a newborn? And when to stop swaddling

In shortCotokim's list counts swaddles only for the first weeks. For a baby in New York City born on March 15, 2027, with balanced amounts, the sleep part of the list is 1 crib, 1 crib mattress, 3 fitted crib sheets, 2 waterproof mattress covers, 2 wearable blankets, 3 swaddles, and 3 baby blankets. Stop swaddling at the first sign that your baby is trying to roll over, whatever the age, and never use a weighted swaddle.

A swaddle is a light blanket wrapped around your baby, or a wearable swaddle that wraps the arms. Cotokim's list counts swaddles for the first weeks only, because swaddling stops when your baby starts trying to roll. How many you need depends mostly on how often you do laundry, since a swaddle goes in the wash after 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.

How many

For the baby in the example, balanced amounts, laundry every two days, with a clothes dryer, the sleep part of the list is: 1 crib, 1 crib mattress, 3 fitted crib sheets, 2 waterproof mattress covers, 2 wearable blankets, 3 swaddles, and 3 baby blankets. The amounts are for the balanced approach, between essential and complete, doing laundry every two days, for a baby in New York City born on March 15, 2027. On your list, they change with your city, your due date, your approach, and how often you do laundry.

The count is a Cotokim proposal: we found no US government health source that gives a number of swaddles. It assumes a short use, the first weeks, and grows if you do laundry less often or have no dryer. Either a swaddle blanket or a wearable swaddle counts.

When to stop: watch your baby, not the calendar

Stop swaddling at the first sign that your baby is trying to roll over, at any age. The NICHD's Safe to Sleep campaign says that once a baby starts to roll over, swaddling increases the risk of suffocation and strangulation, and to stop swaddling when babies start rolling over, usually around 3 months of age 2. "Usually" is not "always", so the signal is your baby, not a date. The CDC says it supports the American Academy of Pediatrics' 2022 safe sleep recommendations 1, and the AAP ties the stop to the first signs of trying to roll, as its page on swaddling safety explains. For safe sleep, Cotokim follows the earlier signal, the stricter of the two.

After the swaddle, for warmth, use a wearable blanket or an extra layer of clothing, with nothing added to the sleep area 2.

Swaddling safely

  • Always on the back. Using the back sleep position for swaddled babies is especially important: a swaddled baby may have trouble moving out of the stomach or side positions 2.
  • It does not lower the risk of SIDS. Swaddling does not reduce SIDS risk, even though some babies are calmer and sleep better swaddled 2.
  • Never weighted. The CPSC says not to use weighted blankets or weighted swaddles 3.
  • Nothing else in the crib. Nothing but a fitted sheet in the crib, bassinet or play yard 3.
Stop swaddling at the first sign that your baby is trying to roll, at any age; the NICHD says rolling usually starts around 3 months 2. A swaddled baby always sleeps on their back 2. No weighted swaddles 3. The number of swaddles on this page is 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

How many swaddles for a newborn?

For the baby in this page's example, balanced amounts: the sleep part of the list is 1 crib, 1 crib mattress, 3 fitted crib sheets, 2 waterproof mattress covers, 2 wearable blankets, 3 swaddles, and 3 baby blankets. The tool above does the math for your city, your due month and your laundry routine.

When should I stop swaddling?

At the first sign that your baby is trying to roll over, whatever the age. The NICHD says to stop swaddling when babies start rolling over 2, and Cotokim follows the earlier signal. Do not wait for a birthday or a set number of weeks.

Does swaddling help prevent SIDS?

No. The NICHD says swaddling does not reduce SIDS risk 2.

What comes after the swaddle?

A wearable blanket or an extra layer of clothing, chosen for the room temperature 2. The crib still holds only a fitted sheet 3.

Can I use a weighted swaddle?

No. The CPSC says not to use weighted blankets or weighted swaddles 3.
