I can't tell if my DD is just going through a growth spurt and that is why she is fussier than usual (for about 4 days now) or if it might be reflux? She seems to get fussy after eating, has been spitting up more (especially when she is on her back) and sometimes gives out a little cry when she is BFing in addition to a strange gagging thing that she has been doing for weeks in between feedings. She's never really been a fussy baby and my DH thinks I am overreacting. I just don't want her to be in pain, but maybe it is the 6 week growth spurt??
