My five month old has been pretty fussy at the breast lately. I think he's teething but not sure. He drools a lot but I don't see anything coming through the gums yet. Lately he has been smashing his face into my breast multiple times after he's been eating for a few minutes. Then he will clampdown and I have to pull him off. I don't remember my first doing this face smashing into the breast thing. Not sure what it could be from. He seems upset or uncomfortable when he does it… Anyone else have a baby do this and figure out why?
