How do I swaddle my baby?
The complete guide to safe, effective swaddling for better newborn sleep
Pediatrician-approved: Follow these techniques to create a safe, comforting swaddle.
Why Swaddle?
Swaddling is an ancient practice that provides newborns with security and comfort similar to the womb environment. When done correctly, it can:
- Mimics womb environment for better transition to outside world
- Reduces startle reflex that can wake sleeping babies
- May help babies sleep longer stretches (30-90 minutes more)
- Can decrease excessive crying by up to 28%
- Helps maintain back-sleeping position (reduces SIDS risk when done properly)
Note: The American Academy of Pediatrics recommends stopping swaddling when babies show signs of rolling over, typically between 2-4 months.
Step-by-Step Swaddling Technique
1
Spread the blanket
- Use a lightweight, breathable blanket (muslin works well)
- Lay it flat in a diamond shape on a safe surface
- Fold down the top corner about 6 inches to create a straight edge
2
Position your baby
- Place baby on their back with neck supported by the folded edge
- Ensure arms are in a natural position at sides
- Keep legs in frog-like position for healthy hip development
3
Wrap right side
- Gently hold baby's right arm straight against their side
- Pull the right corner across body at shoulder level
- Tuck securely under baby's left side
- Keep the wrap snug but not tight - you should fit two fingers between blanket and chest
4
Fold bottom up
- Lift the bottom corner up over baby's feet
- Tuck it into the top of the swaddle near shoulder
- Leave room for legs to move freely in frog position
- Avoid straightening legs or forcing them together
5
Wrap left side
- Hold baby's left arm gently against their side
- Bring left corner across body and tuck under back
- Ensure baby can breathe easily and hips can move
- The swaddle should feel like a firm hug, not a restraint
Critical Safety Guidelines
- Always place swaddled babies on their back to sleep
- Ensure the swaddle allows for hip movement (hips should be able to bend up and out)
- Check baby's temperature frequently - overheating increases SIDS risk
- The swaddle should be snug around arms but loose around hips and legs
- Never cover baby's head or face with the swaddle blanket
- Stop swaddling immediately if baby shows any signs of rolling
When to Transition Away from Swaddling
- When baby shows signs of rolling over (usually 2-4 months)
- If baby consistently breaks out of swaddle
- When baby seems frustrated with being wrapped
- If baby shows preference for sleeping with arms free
Transition tip: Try swaddling with one arm out for a few nights before completely stopping.
