She's 10 months and now, as well as rolling and rocking on all fours, has finally figured out how to get to sitting from lying. She will not stay still. She twizzles in circles, rolls about, sits up, bangs her head on the cot bars. I keep lying her down but the constant up-down is not conducive to sleep! I've tried pinning her with firm hands but she has four limbs and I have two hand and it just feels like a wrestling match. Also not conducive to sleep. Short of pinning her babygrow down like a mounted butterfly, I don't really know how to get her to be still long enough to fall asleep!
