Yesterday we put Em in her cot ostensibly to have her afternoon nap, but also to keep her out of the way while we finished the painting in the bathroom.
I went into her room when finished to put some stuff away. As I was knelt down with my back to her cot, I heard a God almighty bang. First thought was she'd thrown something really heavy out of her cot. Second thought was she doesn't have anything heavy enough to make a thud that loud.
Looking round, I realised she DID have something heavy enough to make a thud that loud - herself. It seems like she saw me on the ground and just decided to catapult out of her cot... and well, she missed me, but landed flat on her back.
I really don't know whether she thought I'd catch her, or even see her. It wasn't like she was making noise that would indicate she wanted picking up or removing from her cot.
All the same, she was no worse for wear (as far as we can tell) and a songs later she'd forgotten all about it.
