DD is nearly five, Reception class started in September. She has slept through 7-7 from two weeks old. Five weeks ago she starts waking four five times a night. Now she wants to be up at six every day. We have bought her an alarm clock and she is very aware what is an acceptable time to get up. Makes no difference. She spends a lot of the time tired and grouchy,she is obviously not getting enough sleep. Have tried later nights,earlier nights. School says there are no problems they are aware of. Any ideas as we are not used to this sleep deprivation thing !
