Screaming through nappy (diaper) changes and outfit swaps.
Updated May 2026
What's probably happening
Newborns dislike being undressed because three things hit at once: cold air on bare skin, loss of containment, and the Moro (startle) reflex when limbs move freely. The reaction is normal and resolves with practice and the speed of the change.
Cold air on bare skin. The change surface and the air feel cold against a body used to being held.
Loss of containment. Open arms and legs trigger the Moro reflex — the limbs shoot out and the baby cries.
A long change feels longer to a newborn. Two short changes are easier than one slow one.
When to escalate
If you need a break:
After a change that ends with both of you in tears, or any time frustration builds: put the baby on their back in the cot (crib). Step out for 5 minutes. Hand over to a partner if one is in the house.
Get immediate medical care:
A high-pitched, weak, or unusual cry that's different from their usual cry during the change.
Crying continues nonstop for 2 hours after the change is finished and the baby is dressed and held.
Fever > 38°C in a baby under 3 months.
