My 7 week old is breastfeeding for up to 2 hours at a time. Latch is fine and he had a tongue tie sorted 4 weeks ago so that's not the problem. Is this normal?! We have been having difficulties with breastfeeding but I'm keen to keep trying and reduce formula feeds but makes me wonder if he's getting enough from breast. As soon as he is finished and unlatches I burp him etc and when I put him down to sleep he wakes back up straight away screaming for more!!
