Our 8 week old has spent the last 2 weeks sleeping on her front (I know, I know, but it was the only way she could sleep due to illness). After visit to health centre today where we were told categorically that we must not put her on her front (didn't realise we were increasing the risk of cot death by 50%!!! :( ) we have spent the day trying to get her to sleep on her back. She has cried for the whole day, occasionally dropping off for 5-10 mins at most. Don't know what to do - should we let her cry it out until she falls asleep (which took an hour earlier and then she only slept for 5 minutes)? We've been soothing and putting her down when alseep, and then she wakes up after a short period. Any advice from anyone would be great. Can't read what she wants / needs as she is crying all the time (I certainly know she is overtired). Usually (both before sleeping on her front and for last two weeks) she slept for 4 hours at a go, would wake for 1-2 hours be fed, changed and played with before settling down to sleep again, and then sleeping for between 4-8 hours at night.
Very worried, and guilt ridden.
