Week 10 at a glance
Week 10 brings deliberate cooing and "conversations," hand-to-mouth exploration, and gradual sleep consolidation for many babies. Wake windows are extending toward 90 minutes. This is an increasingly interactive and rewarding age.
Cooing reaches a new level at 10 weeks — baby is now deliberately experimenting with sounds and noticing that their coos produce a response from you. They may pause, look at you, and wait. This is the earliest form of conversational turn-taking.
Hands are a source of fascination. Baby stares at their own hands and deliberately moves them toward their mouth. This is healthy sensory exploration. You'll soon see them reaching (with some accuracy) toward nearby objects.
Head control in the supported upright position is improving — baby can hold their head up for longer and recover from wobbles more quickly. Continue tummy time sessions (aim for 20–30 minutes total per day) to build the strength needed for rolling.
{callout("info", "Reading baby's cues", "At 10 weeks, baby is communicating more clearly. Turning away, becoming stiff, or fussing mid-play means they're overstimulated and need a break. Tuning into these cues helps prevent overtiredness and meltdowns.")}Feeding patterns may be slightly more predictable now. Breastfed babies typically feed 6–9 times per day; formula-fed babies 5–7 times per day with 120–180 ml (4–6 oz) per feed.
Feeds continue to be efficient (10–20 minutes for breastfed babies). If you're breastfeeding and noticing uneven supply — one breast producing much more — this is common and usually self-corrects. Offering the less-preferred side first can help balance it.
If you're planning to return to work and haven't introduced a bottle yet, now is a good time to begin. Some breastfed babies resist bottles — patience and having someone other than the primary feeder offer it often helps.
Wake windows: 90 minutes is typical, with some babies extending to 100 minutes. Total sleep: 13–14 hours. The overnight longest stretch may be 4–6 hours or more for some babies; others still wake every 2–3 hours — both are within normal range at this age.
A consistent bedtime routine (bath, feed, dim lights, brief wind-down) at this age starts to have a measurable effect on settling speed. Keep it under 30 minutes and as consistent as possible in timing.
Naps remain somewhat unpredictable. Some babies show a clearer "morning nap" around this age (1.5–2 hours after waking), which is a good sign of gradual consolidation. Our guide on wake windows covers what comes next.
No routine visit this week. Continue monitoring wet nappies (5–6+ per day), continued weight gain, and general behaviour. Baby should seem content between feeds for at least part of the day.
Around weeks 8–10, many babies go through a developmental leap with increased fussiness and clinginess for 1–2 weeks. Babywearing, skin-to-skin contact, and frequent feeds help. This is temporary.
⚠️ When to call your pediatrician
not gaining weight · fewer than 5 wet nappies daily · not producing any coos or vocal sounds by week 10 · seems unable to follow a moving object with their eyes · any fever above 38°C (100.4°F)
Week 11 brings stronger head control, longer alert periods, and often some of the most rewarding smiling and cooing yet. Head to week 11, and our Newborn Hub for the full 12-week guide.
Talk back! Cooing is early language — baby is experimenting with sound production and learning that their sounds produce a response. Mimic their sounds, respond with simple words, and pause to 'listen' when they coo. This turn-taking is the foundation of conversation and language development.
This is completely normal and marks the beginning of hand exploration. Babies discover their hands around weeks 8–12 and use them as a sensory tool. It also provides comfort. This is not a sign of early teething — teething typically begins around 4–6 months.
Most sleep consolidation happens gradually between months 3–5. Around 10–12 weeks, many babies start showing a more consistent longest overnight stretch (4–6 hours). True schedule-based naps typically emerge between months 3–5. At 10 weeks, consistent bedtime and wind-down routines are more important than sleep scheduling.
Yes. Around weeks 8–10 many babies go through a period of increased fussiness, clinginess, and disrupted sleep as their brain undergoes a significant developmental shift. This typically lasts 1–2 weeks. Increased contact, babywearing, and patience help most babies through this phase.
