my 2 and a half month old boy sleeps for 5 to 6 hrs at a stretch sometimes at night.. he gets up when he is hungry.. is that ok.. should I wake him up and feed him.. will he get dehydrated..

Nope no need. He will get up when he is hungry. Let feh child follow natural instincts. You will make child cranky if you wake him up. Let him sleep peacefully. you are lucky! :))

Demand feeding is good to follow. Only if you observe that feeds in 24 hours are less than 8 then wake the baby up

bcoz of growth hormone secretion ur baby sleeps longer, dont disturb, it will wake up if it is hungry

Very normal for the child. Let your baby decide.

that's normal my 3 year old used to go to sleep at 9 pm and wake at 9 am with 2 month and he never got dehydrate

Very normal... let him decide... when he hungry he will wake up
