Thanks everyone for your replies. Trish I tried your tip of going in a few mins before 40 mins was up, and the little bugger was already awake, just not crying yet! So I just sat with him through his whole nap and got him to stay asleep for 1.75hrs!! Not very practical, but maybe he'll learn to do this on his own soon. Scarily I realise he may have been getting even less sleep than I realised!

Mumiloo do you co sleep? DS seems to have a very good grasp of night vs day, and I think co sleeping is what did this for us. I've tried a few times lying down with him during the day but this doesn't really work (OTOH I do get a little nap ). We are doing No Cry Sleep Solution too (by doing I mean I've read it hehe haven't gotten any further yet...) and I'm weaning myself off feeding to sleep and have relented and given him a dummy. Not a track I wanted to go down, but it seems to work a bit and we'll deal with that problem later!

I took him to the doctor last week and they said it's unlikely to be reflux since he's gaining weight so well. He did have colicky type issues when he was younger, and we thought reflux for a while but gaviscon didn't really seem to help. I'll take a look into the breast refusal thing, I didn't realise that's what was going on here though I had heard of it.

Do you think it's possible he's just getting his food out quickly? Like I said, he's steadily gaining weight.

Thanks so much girls for your invaluable help

Just in case anyone else is in a similar situation, something else I did in a moment of frustration was swaddle him again (in his cot sheet no less LOL). I did get 2 days of asleep inside 20 mins, which is a big improvement on a few hours. Unfortunately, as with most of my tricks he has cottoned on and it's not working anymore. I guess I'll just have to come up with something else!

Thanks everyone
