So have been propelled into the two eldest sharing (5 and 3) because twins are arriving next year. We need them to share for at least 18 mths if not longer (dependent on house move or not), would you bother with a mid sleeper and youngest on the mattress on the floor underneath the mid sleeper or an ikea kura with the same config? Feels safer than bunks as eldest not up as high and much cheaper but will the smallest end up hating being on the floor? Anyone done this? Thanks
Can you get your hands on a second hand kura, and buy a new one. Use the mattress base plus extra side panels to make a bunk from the kura- it really will be better if you can get the bottom mattress an inch or 2 off the floor.
I had a high sleeper and one of those child beds underneath when mine were that age. The child bed was small enough to for underneath and quite low. I think your 3 year old would probably be quite happy with a mattress on the floor but you can have problems with damp and mildew if you put mattresses direct on the floor.
