I like how the responses in this thread show how normal co-sleeping is, but how unique to each family the set-up is.

My 5yo still co-sleeps, he sleeps all night without stirring pretty much. Over the last couple of months he's wanted to try sleeping in his own bed, but everytime he has woken 2-3 times in the night & needed help settling, and ended up coming back to snuggle with me.
My nearly 3 DS2 is still really insistent on feeding overnight, which I'm trying to stop, but he's not even close to wanting to sleep in his own space. I'm trying hard to stop the overnight feeds, but it's a comfort feed thing, so replacing it with water isn't going to work (even if I could turn BM into water).

I don't let outside pressure get to me too much - afterall, our family sleeping arrangements don't impact any body else in the slightest, so I'm going to do what works for us, not what someone else tells me I "should" be doing. I'm quietly confident that they will eventually want their own bed, and it will be well before they're grown-up. And in the meantime, I'm enjoying the cuddles, and knowing that I'm giving them the security & comfort that they obviously need.
