Ok so Mom dies suddenly and leaves behind a 17year old daughter, it was just the two of them. The 17 year old, Brittany has a father but he is living in a half way house and is a drug addict. Her grandparents are not close to her at all and have told her she has a week to figure out where she wants to live (obvioulsy looking out for best interest they want a safe stable enviornment). She does not want to live with the grandparents as she would be moving out of town in that cenario and living on a farm. She will be 18 in 4 months and is getting ready to start her senior year of high school. She is a very responsible kid and works, gets great grades, etc.

So Brittany came to me and asked to move in with me and my family. I am the manager where she lives first off and was rather close to her and her mom. I have a 3 bedroom and have 3 kids. a girl 7, a boy 5, and a baby boy almost 9 months. I want to take her in because I know we can help her with what she is going through. Also I think staying close to the friends and enviornment here would be healthy for her. But I would want her to have her own room. I do think her grandparents would agree to letting her live here, as my husband and I already spoke to Brittany and explained the house rules.
My question is-Can I put the 7 & 5 year old together in a room because they are of opposite sex, and the baby in my room?

Any guidance would be appreciated. I want to help this girl, but I do not want to break any laws or put my family in jeopardy.

I have never heard of a law that says you cannot have two children in the same room regardless of sex. It would be a different situation if this was a divorce situation and it was in the court order.
