DS, DH and I were all cuddled up in to the same bed over winter and we all got a reasonable night's sleep. I was always a bit sore in the morning though, because I froze in to one spot and didn't move the whole night. But DS slept well and so did DH.

I got a bit jack of it after a while and we encouraged DS to sleep in his cot - which he does. 7pm to 5pm.

I don't see anything wrong with it, but if you do want to teach him to sleep in his own bed later on, that takes a strong will.

I reckon it's whatever you feel like doing. If I didn't have to freeze in to one spot all night, I'd co sleep, but seeing as I'm back at work now I have to have a better quality of sleep - which I don't get worrying about squashing DS.
