All they need is the bed, IIRC. I don’t think DSS requires each child to have his own room.
I recall that when my kids were really little, we just put the box springs and mattresses on the floor. They liked it because it was close to the ground and there was no concern about them falling out of bed. Easy in and out.
I liked it because there was no under the bed to have toys get lost under. No cleaning under the bed.
I understand, however, that DSS wants it to be an actual bad, NOT on the floor. Apparently that’s considered child abuse or neglect or something.
We have the two teenage boys in one room, the two teenage girls in a second room, and the four younger boys in the third. Anyway, they wouldn’t build a new home now when they’re expecting to move out. Maybe one of the little boys will want to homestead someday, to get out of sharing with his brothers.
