I have no idea how to tackle this.
DS wakes up every night, several times a night. It's almost like having a baby. He goes to sleep at 7, but the longest he'll sleep for is until about 11.30, at which point he comes into our bed. That isn't too bad in itself, except on nights like tonight where he has woken at 8.30pm 
He just doesn't like being on his own I think.
I've tried over the years to do controlled crying - failed, gradual retreat - failed, sticker chart - failed. The reason these things have failed is that he is SO strong willed and after a period of time of there being no improvement and/or illness etc I have basically given up.
Just don't know what to do now - please help!!
