My 3 month old baby drinks only 60ml of milk every 3.5 hours. I try feeding her in the middle, but she keeps refusing the bottle. She is formula fed and weighs 4.5 kg. Is this normal? Please help.

A. dear mum baby should gain at least 500 gram per month do not force feed if baby is passing urine 6 to 8 times in 24 hours is active alert and gaining adequate weight then feeding is sufficient do not worry feed on demand
