Bath, interesting about the tummies... DS has always had a strong neck, held up his head the day after he was born (too drugged up to do so on the day) and DH is a definate tummy sleeper. DS hates back sleeping so I may see what the tummy does for him tonight - anything for more than half an hour's sleep at a time! My main insistence with back/side sleeping is that I hate that DH won't cuddle me on his front and I dont want my future DiL to go through those arguments with DS! I hate front sleeping and no cuddles - DS WILL cuddle me LOL. Oh yes, and his future wife. Very selfless of me.

Dee, my DH is on the skinny side and won't co-sleep in case he squishes DS. It's awareness, not weight, that's the problem - I think mothers are naturally more aware of babies than fathers in a lot of cases. I'm a bad mother for covering DS with the duvet, I'm sure (then again, I'm a bad mother for co-sleeping full stop, if you listen to some evil witches), but it's what works for you.
