Baby is 4.5 months and has started rolling over onto his face during the evening when put to bed. He is always put to sleep on his back but rolls over- so I spend my evenings going up to check and roll him back round.
Also he keeps sticking his legs out between the bars of the cot and I don't know how to stop this! My mum suggested bumpers on the cot but when I googled this there was a warning about increased risk of cot death.
Hmm not too sure, but DD (9 weeks tomorrow) is happiest on her side, so we tend to put her down on her side, then she will roll around in her sleep (as I always have done!!), and sometimes her arms/legs end up through the side bars of the crib. She tends to be able to remove them herself though, and it rarely wakes her up, so I don't really see it as a problem. When she was in NNU (she was 4 weeks early so had a 9 day stay in NNU when she was born), she would turn onto her side in her sleep and I asked one of the nurses about it because I was worried (she was right up against the side of the cot!), she told me that she wouldn't be able to get herself into a position that she couldn't get herself out of, so in terms of the 'being on her side' issue, to not worry about it. Not sure about how to stop his legs going through the side though - have you tried sleeping bags?
Once a baby is able to roll over the advice from FSID is to gently roll them back if you see them but not to check through the night. Once they can roll the risks of front sleeping reduce as it is thought to be the inability to turn over that adds to the risk. Have a look at the Lullaby Trust (new name for FSID) website for the whys etc.
