Is My Baby’s Sleep Normal?
A Developmental Guide From 0–12 Months
Sleep is one of the most common sources of stress for new parents.
The question “Is this normal?” often comes from exhaustion — not failure.
The answer, in most cases, is yes.
Newborn Sleep (0–3 Months)
Newborn sleep is:
Irregular
Light
Fragmented
Newborns lack mature sleep cycles and circadian rhythms.
According to the Sleep Foundation, newborns wake frequently to feed and regulate their systems.
