My daughters dad has lost his flat and is currently living on his dads sofa. There’s 8 members in the household. I found out through my daughter she’s been sleeping on the sofa when she’s been staying with her dad. He never told me he lost his flat til I asked him. He says it’s temporary until his dad moves houses and then he will have a small caravan in the front garden and that’s where my daughter will be sleeping when there, it doesn’t have a toilet in it. Is that okay for my 3 year old to sleep in?
