I imagine it MIGHT fit in the sink area, tightly. Can the child stand and reach say the faucets?
Question: Where is the other child sleeping, and how old are they?
My personal issue is having young children sleep in the living room area with the exit door, while we would be in the next room.
Since all the beds are now Queens it wouldn't matter where we slept so I'd likely put a child in the bedroom, then a baby bed in the bedroom-bath which is longer and likely fit better.
We would sleep in living room.
