My 4 yr. old is the same way. Right after she quit waking up in the middle of the night for the bottle, she started waking up crying hysterically. Now that she can talk, I know it is nightmares. It has been so frustrating. I haven't had a good night sleep since she was born & neither has she. I sure hope she outgrows them soon. I feel relieved that somebody else has this problem, not that I'm glad your kids are going through this horrible situation
I wish I had advice to offer, but I need some also. So far when she wakes up, I just tell her to go back to sleep and she is ok. She is used them now. On the nights she doesn't have bad ones, she wakes up and tells me she didn't have bad dreams last night & is so happy. I feel so bad for her. Ok, enough babbling, good luck to everybody with this problem
