My baby is just over 4 weeks old. He is bottle fed breast milk. Hes had a big appetite so far and can have between 4 and 5oz every feed between 3 and 4 hours. This evening, through the night he’s woken up every 2 hours and fallen asleep whilst being fed and hasn’t taken more than 2and a half oz at a time, I’m just wondering if this is normal. I didn’t think bottle bed babies cluster fed or that this was a time where he could be having a growth spurt.
