Does anyone else have this issue: Usually my lo feeds 15 to 20 min per side. In the last 3 days, 3 times he has only fed for 5 to 10 min, and cried hysterically. We called him down and tried again to feed him but he wouldn't take it and again cried hysterically. I burped him a bunch of times. He still had the snorting hunger cue (not sure if that is a true hunger cue). After an hour and a half each time finally got him to eat the 15 min on each side. The pediatrician said that at his age (6 weeks) sometimes they go through phases that they only eat 5 to 7 min total. Not that I don't trust the pediatrician but I wanted to hear other peoples experience with it and also how long that phase lasts.
