Your baby at ten weeks.

Communication is taking off: reliable smiles, long coos, and back-and-forth 'conversations.' Here is what is normal.

Feeding

Feeding is settled and efficient, breast or bottle, often around 4 to 5 oz (120 to 150 ml) per formula feed. Another short growth spurt with hungrier days and more frequent feeds can show up around now and usually passes within two to three days. Ride it out by feeding to appetite; if you breastfeed, the extra demand is how your supply keeps pace.

Sleep

Sleep cycles are still about 45 minutes, but your baby may now link them better in the day, giving the occasional one-to-two-hour nap. Night sleep remains variable, with a gentle trend toward longer stretches across the two-to-three-month window. There is no need to force a schedule yet; a loose, predictable rhythm is plenty.

Diapers

Steady wet and dirty diapers, with the pattern varying by baby and by whether they are breast or formula fed. Comfort and soft stools matter more than exact frequency.

Growth

Muscle tone is improving: your baby can hold their head steady for brief periods when upright and push up onto their forearms in tummy time. Steady weekly weight gain continues, plotted on the growth curve at checks.

This week's leap

Communication is taking off, with reliable social smiles, extended cooing, and prolonged back-and-forth vocal exchanges. Your baby is starting to express different moods through sound and face, not only crying when unhappy. Maximise face-to-face time during alert periods, make exaggerated expressions, and stick your tongue out, as babies this age often try to copy it.

Under three months, 100.4°F (38°C) or above is same-day. Check in if your baby is not fixing and following with their eyes, not responding to your voice, or not smiling socially. A consistently sunken soft spot can signal dehydration, while a bulging one when your baby is calm and upright needs review. Seizure activity, breathing difficulty, or a non-blanching rash is an emergency. None of this is medical advice; every baby is different, and your midwife, health visitor or doctor is the person to ask about your own child.

The calm way to follow all of this is to log it in one tap as it happens, then read the pattern over a few days rather than carrying it in your head. Little Bean shows this same week-by-week guidance inside the app, beside your own baby's log.

Quick answers: 10 weeks

How often should a 10-week-old eat?

Most babies this age take 7 to 9 milk feeds in 24 hours. Feed on demand rather than by the clock; steady weight gain and enough wet diapers are the real signs intake is fine.

How much sleep does a 10-week-old need?

Roughly 14 to 17 hours, often one longer night stretch. Wake windows of about 90 minutes. The range is wide, so treat these as averages rather than targets.

How many wet diapers should a 10-week-old have?

6 or more wet; breastfed stools may space out. A sudden drop in wet diapers is worth a same-day call to your pediatrician.
