We'll need a cot with a removable side for DD, rather than a cot bed which we have for DS, as they'll have to share a room at that point and another cot bed won't fit.
The only one I can find that's actually made to be converted is an Ikea one. Is that right or are there others out there?
I'm assuming we'll need the Ikea mattress? But just regular cot sheets, as it's not very very different to other cot sizes? I can always rig up some fitted sheets if not - I've done that for the cot bed as I found it hard to get funky cot bed sheets.
