Our 4 year old has always been an early bird, but it's getting ridiculous. She always wakes up between 5-5:30am no matter what we do. We've tried earlier bedtimes, later bedtimes, sound machines, we treat it as a night waking but it all makes no difference. She's constantly knackered, falling asleep in the day including at school, behaviour is going downhill etc. Now the clocks are about to change so 5am is about to become 4am and I'm just dreading it. We've followed all the advice from googl z health visitor, sleep charity etc. and nothing has changed. She has a gro clock so she does know she's not meant to be up before 6am. Help!
