Thanks for your input.
He's already got a duck and a teddy that I put in bed with him so I might start saying goodnight to them too. I like the idea of spending a bit more time in his room that isn't sleepy time - maybe tidying up together over the weekend could be a start with that (gotta remember to make it fun).
We already have Hairy Maclary as his special bedtime book for his day and night sleeps (oh boy am I sick of it LOL) and I was going to get Green Sheep as well so maybe we can read one random selection and then the special sleep books. He has books downstairs so I think I'll try and keep some bedroom books in the bedroom.
I've thought about getting a CD but the big problem with that is that he thinks that all discs are DVDs and he gets quite aggro with them and really annoyed when I won't play them for him. Maybe I could just play some music through the computer in another room. Then again he laready has a dummy and a blanky and I don't want to create a situation where he needs a suitcase full of accesories to go to sleep IYKWIM. I've always left the TV on if I was watching it, because I thought that if he can still hear all the usual household noises it reassues him that everything is normal but I might try turning it off and seeing how it works.
I'd best have a look at Lucy's star chart thread and get some star chart ideas.
I like the idea of special bedtime toys. He's car crazy at the moment and keeps taking the cars his grandad gives him to bed with him (they don't seem very cuddly to me but he freaks if I try to take them away so I don't bother) so I might get him some bed cars. I wonder if they make sheets with roads on them that he could 'drive' his cars on.
Thanks again for your help.
