At 3 weeks old my LO (who was 5 weeks early) was guzzling down 4 oz of BM every 3 hours. He would then fuss and moan for 30 mins and end up puking a lot of it up. My pedi was thrilled he was eating so much b/c he was gaining great weight. My LC, however, told me that that was WAY too much, and its no wonder he wasnt BFing well. He's now 7 weeks, and I had reduced him to 3 oz every 3 or so hours. This has been pretty consistent for about a week. For the past 3 days, however, at around 8 am and 2 pm, he just never seems satisfied. I give him the 3 oz and he obviously wants more. I change him after the 3 to sorta let it settle. Then I give him one more oz. He still seems unsettled, but is not screaming. About 30 mins later, he starts to fuss and root, so I give him one more oz. He then falls asleep. Wakes up 30 mins later fussing and rooting, and I give him one more oz. He sleeps for 45 mins or so, still unsettled though, and by this time, its almost time for a full feeding again, and he eats 2-3 oz. I am terrified to overfeed him, but he seems to be okay with eating this much? I'm sure this is normal, and he's probably hit a growth spurt. If so, how long does it usually last for? My LC told me that rooting and fussing can also be a sign of reflux, esp if baby is overfed. I'm confused! How do you know if he's hungry or if he's overfed?!
