Please help! My five month old has been placed to sleep on his back since birth, and while he's never been a great sleeper that's been fine. For a week now, he is just refusing to be laid down on his back to sleep. He happily plays on his back in the day so I don't think it's uncomfortable, he just doesn't want to sleep that way. We normally rock him to sleep and then lay him down and he wriggles a bit then settles to sleep. Now he screams bloody murder when laid down, no matter how asleep he was in arms. He stops crying instantly and goes to sleep if put on his side. It is sometimes then possible to ease him onto his back, but it takes four or five attempts before he doesn't wake up furious in the process, and he will then wake within a maximum of 40 minutes. We have tried leaving him on his side (please don't flame me) but eventually he falls back onto his back and wakes screaming - this takes anywhere between 10 minutes and an hour, so that is the longest stretch of sleep we get. Everyone is totally exhausted. In desperation at 5am this morning I put him on his front (again, please don't flame me) and he slept for two hours - but I just lay there listening to him breathe, terrified he'd stop, so I still didn't sleep! I just don't understand why he could sleep on his back ok-ish (he's woken every two/three hours since the four month sleep regression - he did six to eight hour stretches before that...) until a week ago but now it's such a problem. I just don't know what to do and am so desperate.
Please don't tell me to cosleep - I've tried it, repeatedly, and I just can't sleep, and when I do drift off I wake up in a panic that I've smothered the baby - I'd rather not sleep at all than wake up with that utter panic multiple times a night.
