DD 3 started pre- school about 6 weeks ago. Up until this point she has gone to bed with no problems, asleep within a couple of minutes. I am so surprised that since she has started pre school she doesn't go to sleep, keeps getting up saying she's not tired! I really thought she would be even more tired and I would have to put her to bed earlier. Thought that maybe she was overtired and tried letting her have a nap in the early afternoon but that makes bedtime even later. Help - not sure what to do. She really loves school so I don't think it's to do with anxieties there.
