My son is the same - won't go past the 30-40min cycle. Wakes up crying. Problem is that he won't resettle in his cot. I pat and ssh and sometimes use the dummy. He just seems to cry more to the point of screaming. When I pick him up he stops but then when I try to get him back to sleep (in my arms) he seems to just cry and cry till he falls asleep. Then I can put him down and he'll often sleep another 30 - 45 mins. He's happier for the extra sleep he has, and as he is crying he's showing all the classic tired signs(ie he's not telling me he doesn't want to sleep)...rubbing his eye, pulling his hair, stops crying to do a big yawn and thenstarts again. It's like he's just frustrated he can't get to sleep and nothing I can do, apart from hold him till he cries it out, seems to work. I have tried music (I have music for dreaming), patting, rocking, walking and rocking, a rocking chair but all that works is holding him till he's cried himself to sleep.

Any advice would be great...sorry to hijack thread!
