Swaddling baby — how-to, when to stop and risks

Swaddling — as soothing as the womb

In a nutshell: Swaddling calms many newborns because it simulates the tightness of the womb and dampens the Moro reflex. BUT: There are clear rules for safe swaddling, and it must stop as soon as baby starts rolling over.

Benefits

• ✅ Dampens the Moro reflex (arms jerk → baby wakes themselves)
• ✅ Soothing — simulates the security of the womb
• ✅ Babies sleep longer and more peacefully
• ✅ Especially helpful for colic and fussy periods

Safe swaddling — the rules

1. ONLY on the back — NEVER place a swaddled baby on their stomach!
2. Hips free: Legs must be bent and spread (frog position). Too-tight wrapping → hip dysplasia!
3. Not too tight: 2 fingers should fit between the swaddle and chest
4. Not too warm: No extra sleep sack, monitor room temperature
5. Arms IN or OUT: Some babies like arms free — that's okay too

Swaddling methods

When to stop

STOP IMMEDIATELY if:

• Baby rolls onto their stomach (or shows signs) — usually 3-4 months
• Baby unwraps the swaddle (suffocation risk!)

Transition:

1. First free one arm (1-2 nights)
2. Then free both arms
3. Then switch to a sleep sack

Risks with INCORRECT swaddling

• 🚨 Overheating (too warm, too many layers)
• 🚨 Hip dysplasia (too tight around the hips)
• 🚨 Suffocation (if swaddled baby rolls over)
• 🚨 SIDS risk INCREASES if swaddled baby is on their stomach
