Where can I find a doona cover for a cot sized insert? Ds2 is 23 months and sleeps in his cot with just a sheet covering him. Now that nights are cooling down I want to put a doona in there. I have a cot sized doona insert from when ds1 was in the cot but could never find a cover to fit it. Can only find single sized covers or cot sized embroided quilts but they aren't very thick and don't look very warm for middle of winter. Any ideas where I could get one? Thanks!!
