My baby is a 7 weeks 2 days old and has a HUGE appetite! He has gained weight well and has tons of diapers filled with pee and poo! I know that I am making plenty of milk as I have pumped 6 ounces from each breast when I do pump.
The Dr. and lactation consultant said that he should be going every 2-3 hours between feedings, but I simply feed him when he is hungry. Maybe he is comfort sucking sometimes, I just wanted to make sure that this frequent feeding can happen at any time and not just during the specified growth spurt times (he definitely had a growth spurt at both 5 and 6 weeks where he ate CONSTANTLY).
