oh and as for sleeping in another bed I think that's a fine idea, as long as you know your son will be in to have cuddles in the morning I appreciate the morning cuddles so much when he manages to sleep in his own room. But I had a daughter who slept on her own and my son is a co-sleeper, and the difference between their attitudes to sleep is very interesting. My daughter has only just started going to bed when she's tired instead of staying up til all hours (we're home schoolers, she's 11.5) but my son falls asleep when he's tired, and you really can't wake him up even if you dance around clapping and singing, he just keeps his eyes closed and smiles, and before you know it he's snoring lol
