My DD keeps falling out of her cotbed and I'd really like some suggestions to keep her in there! She lands on a double duvet and readibed and never wakes up when she does it, unless she's cold! There are now so many things to protect her on the floor that I can hardly get in the room! I did buy a Tomy bedrail, but it was too wide and the shop were no help at all when I returned it. Any ideas, please.
