FirstWeeksYour baby at 10 weeks: longer stretches
Medically-informed · Sources: CDC · Updated June 2026
Night sleep often consolidates a little — some babies gift you a 4–6 hour stretch.
What’s happening
Night sleep matures
Many babies begin sleeping one longer block at night. Many others don't yet — both are commonly seen at this age.
Hands become fascinating
Staring at hands, bringing them together, gnawing on fists — baby is discovering the body.
Drool arrives
Salivary glands wake up around now. Drooling alone isn't teething yet.
What to do
- Keep night interactions boring: dim light, quiet voice, no play
- Protect your own sleep during the long stretch — go to bed early once
- Offer safe objects to grasp and mouth
When to check in
Baby who slept longer stretches suddenly waking hourly for many nights plus feeding poorly — worth a pediatrician chat.
Skills to watch this week

- 6–10Smoother arm and leg motion — Newborn jerkiness gives way to flowing movement.
- 9–13Bats and swipes at objects — Aims at dangling toys; contact is the victory.
- 9–13Briefly holds a toy — Keeps a light rattle in the grip for a few seconds.
- 9–13Pushes up on forearms — Mini push-ups raise the chest in tummy time.
Every baby has their own pace — ranges are typical, not deadlines.
