thanks guys for your responses.
Aiden does have his favourite teddy... well, its actually a bunny rabbit. He has a night light, and a radio playing as well.
I was talking to a friend today, who's little girl is about a month younger, and she is going thru the same thing.
I said to DH this morning that perhaps I should just bring him into bed with us, we are both abit worried about creating a habit, but, I feel like what ever i do to get him back to sleep (other then CC, which i am not keen on) is going to create a habit. Be it a bottle, rocking, patting etc. At least this way, i can get some rest.
He goes down for his day sleeps beautifully, mostly just put him in his cot, and walk out. And he goes off to sleep on his own.
I guess if i put him to bed a night, if he wakes, give him a few shots at going back to sleep, and if no luck, then, bring him to bed before he wakes to much, and once he goes into a deep sleep, put him back into his own cot.
It must be a security thing that they go thru at this age? I hope it doesnt last long.

Kym - my aim was to get Aiden sleeping thru before the new bub comes along.. maybe i will have to revise my goal to school as well!
