Dd2 is 7 and doesn't sleep, last night she finally gave in at 1am!! She is tired and grumpy all the time. She is unco-opertive and screams all day. She fights with her siblings. I know its because she isn't getting enough sleep, but I can't make her sleep. She has bags under her eyes. She goes to bed at 7:30pm with a warm milk and a story, but will just stay awake, she screams all night. I have had enough... help!!!
