My 12 week old has been refusing to BF after 3hrs. She starts to eat and after 3mins is screaming at me. I have tried waiting 3.5 hrs and she still seems not hungry. She is definately not able to stay awake past 1.5hrs. She usually yawns after 1.25hrs. I have to wake her from 2 out of 3 naps a day so she can't be that hungry or she would not sleep - right? Here's the catch though, this week, she has added a night feed because she is not getting enough in the day. She is now up at 10pm, 1pm and 4pm to eat. Also, she just started rolling over and this has caused a lot of wakings. Any advice would be greatly appreciated!!!!
