Our house is a pretty standard 3 bed semi with dormer windows upstairs. The third "bedroom" is tiny and has lie-ins from the stair/dormer windows so there's not much floor or head space round the edges of the room. DS2 is getting too big for his toddler bed, but if we put a full size single in there, there won't be room for anything else. Has anyone else found a creative solution to this problem? I was thinking about a mid sleeper but they all seem huge. Thanks.
