My dd has recently moved from her moses basket to her cot and she is definitely making the most of the new space. Every night she moves around the cot and ends up with her head pushed against the side which wakes her up. I've got a bumper in place to protect her from the bars but she still gets very upset when she hits the side. Does anyone have any ideas on how to keep her in one place? She also ends up freezing because she comes out from under her blanket (sleeping bags don't work because they bunch up around her legs and she gets frustrated). Any ideas?
