DD is almost two and had been sleeping through fairly consistently until we started potty training. She's done well, but seems to have night trained herself too and now doesn't pee while asleep, so wakes me in the early hours to help her go to the potty. She sleeps in a big 2.5 tog sleepsuit thing that she's got no hope of getting out of herself and the whole palaver seems to fully wake her. I want to give her some two-piece pyjamas that she can take down herself to use the potty, but she won't sleep under the covers and gets cold with just pyjamas on (even the fleecy ones), then wakes in the night and wants to get into our bed. Any suggestions on how we can get her used to sleeping under the covers?
