i cant say why he's doing this but i just wanted to say that my dd used to be an angel when it came to bed time, 7pm she would actually ask to go to bed, then all of a sudden she changed, (this was a long time ago, even before ds came along) come 7pm she fights and screams cause she doesnt want to go to bed, she also wakes several times a night but still gets up at 7am, but if she wakes at like 5am, she will want to get up and scream blue murder until she does get up. this has been going on for well over a year now and we have just gotten used to it. i know some people may disagree but we have put a tele and dvd player in her bedroom, so if she does wake at 5 am we put her favourite film (cinderella) on for her which she will fall back to sleep to. we've tried the whole putting her bed later thing and that doesnt work either apart from making her cranky the next day
im sorry i cant say anything to help or why he's doing it but i just wanted to let you know that he isnt the only one who does it
