Swaddle your baby snugly in a lightweight blanket

Wrap your baby snugly in a lightweight blanket with arms tucked at the sides, leaving the hips loose enough to bend naturally. Swaddling recreates the snug feeling of the womb and reduces the startle (Moro) reflex that often wakes or upsets newborns.

Why It Works

The gentle, even pressure of a swaddle mimics the confined space of the uterus, helping newborns feel secure. The AAP recognizes swaddling as a calming technique when done correctly. Reducing the startle reflex prevents babies from flailing and startling themselves awake or into deeper crying.

Tips

• Always place a swaddled baby on their back to reduce SIDS risk -- never on the stomach or side
• Stop swaddling once your baby shows signs of rolling over, typically around 2-4 months
• Keep the swaddle snug around the chest but loose at the hips to allow healthy hip development
• Use a thin, breathable fabric like muslin to prevent overheating
• Pre-made swaddle sacks with velcro or zippers are easier for beginners than traditional blanket wrapping
• If your baby resists having arms pinned, try a swaddle with one or both arms out
