My 9 1/2 month old pretty good sleeper has started moving lots in the night and is getting really twisted up in her sleeping bag.. her current favourite sleeping position is on her knees with bum in the air! Can't believe she is comfortable but she insists. Anyway, I know that the general advice is to wait until they are 1 before introducing duvets and pillow but I'm sure she will be more comfortable this way. I'm just worried that she'll go back to kicking off the covers and getting cold.. any advice? experience of this? Many thanks!
