My 8 week old cluster feeds sometimes and wants to nurse every hour until bedtime. Just now he was on the left breast and suddenly either spit up or vomited what looked like all the milk he had consumed....and he kept on going like it didn't even happen. Is he even hungry?? I then gave him the right breast and a few minutes in he did the same thing. He acted like he wanted to continue but I put him in his cradle swing and he's happy as can be. I'm sure he will get fussy in an hour and want to feed again. What is going on with this vomiting of milk? It seemed like more than just spit up.
