My DD is 15 months and for the last couple she has been waking herself (and us!) quite a lot by crashing against the sides of her cot, or the top end - she sort of gets into a crawling position in her sleep, then ends up bent round about 90 degrees in the corner of the cot. She gets in these uncomfortable positions then cries till put back in a sensible position (presumably not fully awake so doesn't move herself). It seems to happen when otherwise restless (teething) but really doesn't help the tired/grumpy/teething situation. She sleeps in a grobag. Anyone got any thoughts?
