trishalishous thanks for your reply. I didn't actually read the article you posted as I have decided I have read/ researched / worried myself sick over the right thing to do. We have been to sleep school a number of times since and I have been a little "tougher" on him but not leaving him to CIO, just trying to set limits on the fact that he should be asleep at 2am in the morning!!!!

Currently he is happy sleeping on a mattress on my bedroom floor, no crying to sleep, just cuddles. Only problem is, its just me who can do it. If I ever want to go out at night even for a couple of hours it means he wakes up, freaks I am not there and then stays up till I get home. Hopefully it will get better in time.
