My little boy (12 weeks) drinks roughly 7oz x5 every 3hours. He sleeps 1930ish-0630ish with no bottle.
My little boy has a bottle every 3/4 hours and usually around 180ml during the day and then sleeps from 8pm-5am has a bottle and goes back to sleep till 8am
My baby drinks expressed breast milk and I fed on demand, no routine.
My little girl (14 weeks) lets me know when she’s hungry. On average this is every 3 hours. Sometimes she does 2 and a half between feeds and sometimes 3 and a half. She is currently drinking 180ml per feed (6oz) and most of the time she has all of it. During the day she has 5 feeds between 7am-7pm and a feed in the middle of her night sleep so around 2/3am
