Advice please - twice lately we have found our 4 month old has woken up and rotated herself round then stuck her legs through the bars on the cot. She has not cried, in fact she looked rather pleased with herself this afternoon! I am worried though that she could hurt herself. Normally she is in a Grobag which I think would prevent thisbut it's too hot at the moment so she's just in a body suit. I know cot bumpers are not advisable but I am concerned she will injure her legs. Any suggestions please?
