hi
we have this cotbed from kiddicare. i want a double bedguard that will fit both sides for the next year that we will be using it in cotbed mode. i bought one from kiddicare yesterday and spent two hours assembling it, and it didn't fit despite the website and box saying it would 
does anyone have a good one that might fit? the problem is that the sides are slightly raised to create a kind of u shape in the base for the mattress to slot into, and the double bedguard just doesn't slot in.
thanks!
