My dd is 3 and a half weeks old...bottle feeding and is normally very relaxed and sleeps fairly well throughout the day. Today has been awful. She wont settle unless on me...and even then very fitfully. It's really unlike her. Shes feeding well...taking 5oz but doesn't even settle particularly well after a feed even like she did. Any words of advice? I'm hoping its just an off day but I'm genuinely worried that she's now going to be like this for the foreseeable and I've spent no time with my older kids....help!
