Plz do check whether baby is getting enough milk ma.. Or else u can take medicines to increase ur breastmilk secreations.

If your breast milk is adequate baby would feed for  about 15 min on each breast and would sleep thereafter for atleast 2-3 hours. Babies at this age have a tendency to be awake at night and sleep during the day because when they are in utero(before birth) they sleep during the day as mother works in the day and amniotic fluid around the baby moves to provide sensations like a swing so after being born it takes about 2-3 months to acclimatize. Still check your breast milk volume and take enough fluids to increase production of milk. Things will be better soon.

Hi, This is normal. Babies at this age do not sleep well at night.
