Hi Kirsty - I hear ya! I have a picture of Hannah's arms and legs hanging out of her cot on her website. Pretty funny photo opportunity, but not funny when she continually woke herself up doing it! In the cooler months, the grobag seemed to do the trick for us. Now that it's hotter, Hannah is sleeping in her portacot a lot, which has mesh sides that don't wake her up when she bangs against them... If you have a portacot, it might be worth trying? Just an idea!
