Brain maturation causes sleep cycle changes. Baby may wake more frequently at night and resist naps. This is permanent — baby is developing adult-like sleep cycles.

Sleep Tips for a 4 Month Old
The 4-month sleep regression is real and caused by permanent brain changes in sleep cycles.
Baby now cycles between light and deep sleep like adults — they may wake between cycles.
This is the earliest age most pediatricians consider gentle sleep training appropriate.
If using a swaddle, transition to arms-out sleep sack NOW if you haven't already.
Nap transitions: some babies drop from 4 to 3 naps this month.
