I have a bedside co-sleeper cot and up until a few nights ago it was working so well! Isobel would feed, then go back to her bed and sleep until the next feed. Now she seems unable to settle in her bed and wants to stay in bed with me instead. As soon as I move her back over she fusses but them falls asleep straight away when she is in my bed! The idea of the cot was so that she felt she was in our bed without actually being there if you see what I mean! Any ideas?
