my 5 year old has finally just fallen asleep now!
i hear you girlfriends. My DD is a night owl and her twin brother is a morning person. Sometimes i had 5 hours in between one going to sleep and one waking- and they are at school!!!
The first time i got a full nite sleep was when they were 3 years old! and that was only once a week on a average
tried everything as well
just remember that they won't have sleeping issued when they are 21 years old!!
its is a phase and they will get through it- we just have to keep sane whilst they are going through it!!!
better go and get some sleep now as DS will be up in 6 hours!
