I have a 2 year old girl....so sleep has been hard to come by anyways, but now it has almost disappeared. Every night she wakes up screaming at the top of her lungs at 2am and sometimes again at 4am. It takes her forever to fall back asleep. I can find no reason for her doing this. She is a healthy happy 2 yr old. We always ask her if she "hurts" anywhere, and for her to show us the "ouchy" but nothing. I have checked to see if she is getting new teeth, even gave her tylenol before bed once. I have tried mylicon in case it was gas also. I have told the doctor and he said she seems fine, he tested her for a few things but there was nothing to find. I am afraid that this is becoming a nightly habit. Has anyone gone through this? Could it be night terrors? Does anyone have any advice at all? Thanks for listening.....I hope there is an answer because I think it is affecting our health...we all have a cold right now and sleep would be heaven.
