Why does my baby wake up every time I transfer them to the crib?

Babies often wake during a crib transfer because the move changes several things at once: they feel their support shift, lose your warmth and motion, and may be in a lighter stage of sleep when you move them.

A few common reasons:

• Startle reflex: Lowering a baby can trigger a reflexive startle, especially if they feel a sudden change in support.
• Light sleep: If they’re still in a lighter sleep stage, even a small change can wake them.
• Temperature and sensory change: Your body is warm and moving; the crib is cooler, flatter, and quieter.

Things that may help:

• Wait until they’re in a deeper sleep before transferring, if possible.
• Lower them slowly and keep your hands on them for a moment after placing them down.
• Try a feet-first lowering rather than lowering the head first.
• Use white noise to make the transition less noticeable.
• Keep the sleep space consistent so the crib doesn’t feel dramatically different from your arms.

For safety, follow safe sleep guidance: put your baby on their back on a firm, flat mattress with no loose blankets, pillows, bumpers, or stuffed toys. Avoid warming the crib with a heating pad or hot water bottle, and don’t leave any warming device in the crib with the baby.
