My 2 week old son is eating constantly. After doing some searching around on this site I know that he is probably going through a growth spurt, but it worries me that he spits up pretty often after eating lately. Today he spit up around 4 times - not projectile or anything, just flowing out. He usually will spit up after he has fallen asleep on the breast and while I am burping him. He doesn't seem bothered or in any pain. Each time he spits up, he immediately beings rooting, sucking on his hands and eventually crying if he is not nursed again soon. Many times he will just fall asleep right after I put him back on the breast.
My question is - how do I know the difference between when he wants to comfort nurse and when he is actually hungry. I know that I should be feeding on demand and that there is no harm in comfort nursing if that's all he wants to do - but on days like today when he spits up so often, I wonder if I'm doing the right thing by continuing to put him on the breast when I don't believe he is truly hungry anymore. Tonight I ended up giving him a pacifier after he spit up twice and he fell asleep pretty quickly.
I'm open to all advice and suggestions
