Is there some kind of feeding regression at 4mo to go with the sleep regression? DD has never been a wonderful feeder (issues from forceps birth and tongue tie), but since her sleep got worse, her feeding has too. She has started chewing again which I was just getting her out of doing, and coincidentally or not I now have blebs on both nipples which I haven't had before. Also she seems to have developed a real problem with trapped wind; she repeatedly comes off and cries during a feed, and seems to be straining to get the wind out, and DH and I have trouble winding her too. If I manage to feed her to sleep she is nearly impossible to wind and wakes up with it after about half an hour. I hate seeing her so unhappy and it's wearing me out too.
