Mel, do you let him have any small toys in his cot? Or board books? Do you think if you read him a few cuddly stories before bed, then put him in his cot and let him "read" to himself for a while, that he would respond well?

Does he have a night light?

I was just thinking that then, when he wakes in the middle of the night, that a little "read" might be the thing that sends him back off again, by himself?

Dunno........
