she is driving me potty right now. she is 5 and goes to bed around 8-8.30pm. she is usually not asleep before 10 at the earliest, but it has been past midnight. she is in and out of her bed, and finding any excuse to call me. its driving me spare. i have 3 other kids and none of them do it, she shares with her 6 year old sister who need to be up at 7 for school (goes to special school and gets picked up at 7.45am) and she is knackered because dd2 just doesnt stop. she is otherwise stroppy and bad tempered but perfectly normal in every other way. what can i do?
