FirstWeeksYour baby at 14 weeks: three-month shift
Medically-informed · Sources: CDC · Updated June 2026
The fourth trimester is behind you. A hungrier stretch is commonly seen around now — and awake time turns genuinely social.
What’s happening
Another appetite jump
A growth spurt around three months is commonly seen: more feeds, more clinginess for a few days, then it settles.
Hands are the main toy
Staring at hands, clasping them, pulling everything to the mouth — this is how the brain maps the body.
Drool turns on
Salivary glands are fully awake. Drool alone isn't teething yet — teeth commonly arrive later.
What to do
- Feed on demand through the spurt — supply follows
- Rotate two or three simple graspable toys
- Keep the wind-down routine steady even on hungry days
When to check in
Feeding refusal (not just fussiness), fewer wet diapers, or fever 100.4°F+ — call your pediatrician.
