my boy, who is 3 and half month old sleeps all the night and wont wake up for milk. i wake him up for every one hr and feed him. im having doubt that is he jst suckling r drinking also... how to know that

hi mounika if baby's pre count is 6-7times and baby has gained weight then baby is doing well.also if baby is comfortable and sleeping well means his tummy is full.

you can give a gap if about 90 mins between feeds Monika

Agree with Sonia. If your baby is peeing at least 6 to 7 times and is happy and active, do not worry.
