Enigma, you are lucky that your DD sleeps well when you co-sleep. I love having my boys in bed with me, but for some reason neither of them has ever slept well when in bed with us. I think co-sleeping is natural and the way nature intended so I am sad that it is just not for us.

If I was you I would do what feels right. If you enjoy co-sleeping, go for it. If you are worried that she will have the same anxiety you did, I am sure you can find ways to make her feel secure without you down the track. You could introduce other comforters and ease her out of your bed by starting with a matress on the floor, then moving her to another room and you stay with her while she falls asleep etc until she is secure by herself. Worry about that when the time comes.

As for how to make it work, I think everyone is different. I know of lots of people who's DHs sleep elsewhere. Others manage to fit into one bed with no worries. I know of one family who were renovating anyway, so they put matresses on the floor and all slept next to each other on the mattresses on the floor. I am sure you will figure out what works for you.

Enjoy your time sleeping with DD, I'm jealous!! And they grow up so quickly!!
