## TLDR

- Stop swaddling as soon as your baby shows signs of trying to roll, often around 2 months; watch from about 8 weeks.
- Switch to an ordinary, unweighted arms-out sleep sack. Many babies adjust in 3-7 nights.
- Once they roll both ways on their own, you don't need to turn them back. Keep putting them down on their back.

## When to stop

- **Stop swaddling for sleep as soon as your baby shows signs of trying to roll,** even if they
  haven't rolled yet. Signs: rocking onto a side, kicking a leg over, arching and twisting.
- The AAP notes rolling attempts often begin around 2 months, sometimes earlier, while other babies
  start closer to 3 to 4 months. Watch closely from about 8 weeks; don't wait for a set birthday.
- A swaddled baby who rolls onto their tummy may not be able to push up or turn back, which
  raises the risk of suffocation. That's why the rule is firm.
- Also stop if the baby keeps breaking out of the swaddle; loose fabric in the crib is a hazard.

## What to use instead

- An **arms-out sleep sack** (wearable blanket). It keeps a baby warm without loose bedding.
- Choose an ordinary, unweighted one. The AAP advises against weighted sleep sacks, swaddles and
  blankets.
- "Transition" products that hold the arms up or restrict movement aren't needed. If the baby can
  roll, their arms should be free.

## Three ways to make the switch

1. **One arm out.** For a few nights swaddle with one arm free, then both arms free. Only use this
   if your baby isn't yet showing rolling signs.
2. **Straight to arms-out.** Many babies adjust within 3 to 7 nights. It's the right choice once
   rolling has started.
3. **Naps first or nights first.** Some families switch bedtime first, when sleep pressure is
   highest, then naps.

## Easing the first nights

- Keep everything else the same: the bedtime routine, white noise, dark room, the same sleep sack
  for naps and nights.
- Expect startles and arm flailing. The startle reflex fades over the first 4 to 6 months.
- Practice rolling during the day with lots of floor and tummy time, so your baby learns to
  move in and out of positions (see the tummy time guide).
- Help a little more for a few nights: a hand on the chest, shushing, or a brief pick-up to calm.
  Pull back as they adjust.
- Offer a pacifier at sleep time if you use one; it doesn't need to be put back in once asleep.

## Hip-healthy swaddling, while you still swaddle

- Snug around the chest, loose around the hips so the legs can bend up and out like a frog.
- Back to sleep, every sleep. Never place a swaddled baby on their side or tummy.
- Keep the head uncovered and avoid overheating: one layer more than an adult would wear, at most.

## Once your baby rolls

- Put them down on their back every time. If they roll on their own both ways, you don't need to
  turn them back.
- Keep the crib bare: fitted sheet only. See the safe sleep guide and the 4-month sleep regression
  guide, which often overlaps with this switch.

## When to check in

- Mention it at the next visit if your baby isn't trying to roll or bear weight on their arms by
  about 6 months.
- If sleep falls apart for more than two weeks after the switch, talk with the pediatrician about
  next steps.
