Newborn feeding every 4hrs at night

My baby is 1 month 1 week and full FM. He’s feeding on 60-80ml every 2-3 hours (usually by the 2nd hour he’s already crying for milk) during the day, but at night, he would usually only wake up every 3+ or 4 hours. So usually at night (after 12am) we would only feed him when he’s crying for milk which usually is like every 4hours. Is that ok? Recently we went to polyclinic and he’s still gaining quite a good number of weight, which doc said he’s gaining a good weight and also his height and head circumference is good. 3kg at birth, 4.4kg @ 1 month old. Can i still continue to feed him every 4 hrs at night? #firsttimemom
