I have been exclusively BFing my 9 week old and recently I think he gets too full! Especially at night, when I feed him in bed, I have a hard time gauging how much he's getting b/c I"m so drowsy and he will sometimes vomit ALOT !! This morning, after nursing in bed off and on for 1 hour, we got out of bed, I showered and then nursed again before I left for work. He seemed to want more, kept eating (although looked full), then started gagging and vomited a ton!! He's definitely a healthy size baby, probably 13 pounds now. Should I only feed him for so many minutes, or go by how soft my breasts feel? It's hard to know b/c when he's nursing, he often pulls off and then goes back on, so sometimes I don't know when he's done, especially since he doesn't always fall asleep after a feeding! Help!
