My daughter turned 1 almost 3 weeks ago and since then she started to wake up at night for 2-3 hours (every 2 days)! At first it was a tooth that was coming in , but now we don't know what is the problem. We give her milk sometimes , check her diaper and nothing works! She has pacifiers and when she wakes up she throws them on the floor and starts screaming. We are tired and don't know what to do. We did try to let her fall asleep, but she keeps crying .
