A swaddle can be a powerful tool to help a newborn sleep well. But knowing when and how to transition out of a swaddle is not only important for safety but also helps prevent your baby from becoming dependent on it for sleep. Teaching your baby how to fall asleep without relying on something external benefits the entire family and fosters healthy sleep habits.
The Benefits of Swaddling Your Baby
Swaddling offers several advantages for newborn sleep:
Soothes a colicky baby – The gentle pressure of a swaddle provides comfort and security, mimicking the womb environment.
Regulates temperature – Newborns struggle to self-regulate body temperature, and a swaddle helps keep them warm. Always check your baby’s body (not extremities) to ensure they feel warm but not hot or cold.
Reduces startle reflex – Babies have an involuntary startle reflex that can wake them up. A snug swaddle prevents sudden movements, promoting longer sleep stretches.
Calms a crying baby – The snugness of a swaddle helps babies feel secure, reducing fussiness and promoting relaxation.
Supports family sleep – When your baby sleeps better, the entire household benefits from improved rest.
When to Use a Swaddle and When to Transition Out
Always follow AAP (American Academy of Pediatrics) guidelines for safe sleep. Swaddling can begin as soon as your baby is born. However, knowing when to stop swaddling is crucial for safety.
The AAP recommends transitioning out of the swaddle when your baby shows signs of rolling, typically between 8-12 weeks. Rolling while swaddled poses a suffocation risk, so it’s essential to start the transition before your baby rolls unintentionally. Many babies begin showing early signs of rolling around 10 weeks of age.
What Does Baby Wear After the Swaddle?
Once your baby transitions out of the swaddle, you have two options:
Basic Sleep Sack – Choose a non-weighted sleep sack, as weighted versions are not AAP-recommended.
Transitional Swaddle – A transitional swaddle, like the Zippadee Zip, provides a snug feel while allowing free movement, making the transition smoother. However, babies who self-soothe by sucking on their fingers may find this restrictive.

How to Transition to a Sleep Sack
Gradually transitioning out of the swaddle can make the process smoother for your baby:
Start with one arm out – Choose a nap or bedtime and swaddle baby with one arm free.
Switch arms – For the next sleep period, swaddle with the opposite arm out.
Alternate arms for 3-4 days – Continue alternating arms out before completely stopping swaddling.
Use a sleep sack – Transition your baby to a sleep sack for safe, comfortable sleep.
You may notice your baby moving more once out of the swaddle—this is a good thing! Increased movement supports mobility development. Be sure to add more tummy time during wake windows to strengthen muscles.
Final Takeaway
Swaddling is a fantastic tool for newborns, but you must transition out of the swaddle before your baby starts rolling. To be safe, plan to make the switch before 10 weeks of age. With a gradual approach and the right sleep sack, your baby will adapt smoothly, ensuring better sleep for the whole family!
