my baby born at 36 weeks. 3 day old drinking 60ml breastmilk 1 week old drinking 90ml 2 hourly. 1 month old 120ml 2 hourly. it depend on baby individual intake. some drink more some drink less. my advice is follow baby's cue don't just go by timing. offer your boobs for cluster feed.
breastmilk easy to digest that's y they tend to get hungry again. just feed on her demand
