Hugs. I'm sure nightweaning can be done while still co-sleeping, but for us that did not work. DS needed to be in his own bed, in his own room, for nightweaning to work for us. We still co-sleep in the mornings, but at night DS sleeps in his own room. At first I was sad about it, but we all ended up sleeping so much better after that change. Good luck!
