Thanks for your replies.

Have had such a crappy day from feeling so tired, and then feeling guilty cause I'm not playing with DS like I usually would . Then, to make matters worse he refused to have his afternoon sleep .

Ginger: I haven't tried the entire night with him in our bed, mainly because this would mean me having to go to bed at 7.30pm! Last night I brought him in when he woke the first time (about 10.30pm). I actually think he slept slightly better - he woke and went back to sleep no problems the first time he woke, but then he woke at 4.30am and wouldn't go back to sleep then. I can't tell if him sleeping in our bed really does anything to help.

Lollybaby: We haven' wrapped DS since he was 2 months - he used to wriggle out of it, and he slept fine when we stopped (all those months ago). DS sleeps in a cot in his own room. He slept in a bassinet until he was 4.5 months, and moved into his cot (which was then in our room) without any problems. We then moved him into his own room at 6.5 months. He sleeps fine in his cot through the day, so I don't know if the sleeping environment is the problem - though of course I'll never really know.
It's possible something in his room is distracting him. He has some soft toys in his cot... We've started using a night light recently, cause I thought maybe the pitch black was scaring him, but the night light hasn't made things any better, or any worse.

Ali: I've PM's you - thanks hun . Sound machine / music might be worth a go actually. I've never tried anything like that. I tried DS with a dummy ages ago, and it worked for about a week until he decided it was a toy. Now I give him a dummy, he pulls it straight out to look at it, then chews on it or shakes it like a rattle.

Winter: I'll try that too, going in and talking to him - I'll try almost anything the way I'm feeling today.
Haha - if all else fails your set up may be what we end up doing - cause when he wakes up that early there's really nothing we can do with him to get him to sleep.

Thanks for all your replies - keep 'em coming, I'm desperate!
