My DD is 3 1/2, we'll be moving house soon and I really want to buy her one of those cabin beds. THe room she's going to is pretty small and I like the idea of her having as much available space to play as possible. Is she too young for these? I know that the beds tend to have barriers ont eh side to stop the wee ones falling out, and we've also got a travel one I could use, but I don't want to endager her safety for the sake of a piece of furniture, so any help/ thoughts greatefully received (bed I am looking at is alos around £800 so REALLY don't want to f*ck up such an expensive purchase as don't have the spare cash, we've been saving up for this for ages!)
