DD (4) has always been a tricky customer. Her behaviour at home towards two older brothers, me and DH is very aggressive (tho' she's better at school, I'm told). She's always found it difficult to separate from us to go to nursery, and now to school. She's never really slept through the night and comes in to our bed every night. DH takes her back to her own bed, where she screams and screams, whether he stays with her or not. Her sleep problems have become really bad over the last two weeks - she's terrified of going to sleep, says she can hear frightening noises, wakes regularly unless she's in with us. We're all exhausted, all the time. I'm sure that the aggression, the problems with separation, and the sleep issues are all connected, but I really don't know how to begin to approach them. Any thoughts, anyone?
