My daughter is 10 month old and has been in her cot for the last few months in her own room. We put her to the bottom of her cot every night but wakes up half way through the night with her head squashed against the top of the cot. We bought a bed bumper to go around the top of her cot to try and stop her from banging her head but when she’s moving during the night it’s not protecting her the way we wanted… Does anyone have any recommendation on what I can do to stop her from banging her head.
