Around two months many babies have their first round of shots, and the big, deliberate smiles really arrive. Here is what to expect.
Typical day · week 8
- Feeds: 7 to 9 milk feeds in 24 hours
- Sleep: 14 to 17 hours, often one longer night stretch
- Naps: Wake windows of about 90 minutes
- Diapers: 6 or more wet; breastfed stools may space out
Feeding
The same feeding rhythm holds, around 4 to 5 oz (120 to 150 ml) per formula feed or a similar pattern at the breast, several times across the day. Appetite can jump for a day or two around a growth spurt or after shots; follow your baby's lead rather than a fixed amount. Steady diapers and contentment between feeds tell you intake is enough, whichever way you feed.
Sleep
Sleep is still variable. A small number of babies begin a longer overnight stretch around now, but most continue to wake at least twice, and that is entirely expected. After vaccinations your baby may be more unsettled and wakeful for a day or two, and extra holding and feeding through it is exactly right.
Diapers
Regular wet and dirty diapers are the reassuring sign. In the day or two after shots you may notice slightly fussier feeding and an off diaper pattern, which settles quickly. Breastfed stools stay soft and can be infrequent; formula stools are firmer and more regular.
Growth
A steady gain of about 5 to 7 oz (150 to 200 g) a week is typical, and your baby is visibly filling out in the face and limbs. Growth is tracked on the curve at checks rather than at home.
This week's leap
Smiles are broad and deliberate now, the first laughing-like sounds may appear, and your baby follows faces and objects across their whole field of vision, staying awake and alert for longer each day. Many countries give a first vaccination round around two months, though the exact schedule varies, so check your local one. It is completely normal for a baby to be unsettled, run a mild temperature and be extra clingy for 24 to 48 hours afterward; infant acetaminophen at the age-appropriate dose can ease the discomfort, and a firm lump at the injection site is normal and may last a few weeks.
After vaccination, seek urgent help for a temperature above 102.2°F (39°C), a seizure, a rash or hives, a pale or floppy baby, or one unusually hard to rouse. Outside of shots, your baby is still under three months, so the 100.4°F (38°C) same-day threshold applies. An injection site that becomes very swollen, red, warm and painful in the days afterward can occasionally mean a skin infection rather than a normal reaction, and is worth a call. 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: 8 weeks
How often should a 8-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 8-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 8-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.
