why does baby smile in sleep?

The real reply from the in-app AI advisor
Baby smiling in sleep is quite common and normal. The main reason is that the baby's brain continues developing rapidly during active sleep (REM) cycles. In newborns, about half of sleep is spent in REM; during this period the brain works as intensely as when awake, nerve connections strengthen and new skills are processed. Involuntary facial muscle contractions appear as a reflexive smile — they don't necessarily carry any dream or emotion meaning. Generally after 2-3 months when babies start smiling socially while awake, sleep smiling decreases but doesn't completely disappear. If sudden intense smiling wakes baby, or body spasms, bluish discoloration follow, consult your pediatrician; otherwise it's not something to worry about.
