OP has a guest room. She can put the other kids in her kids rooms on air mattresses and give the adults her room or put them all in her room and she take the guest room. |
OP I would not ask Au Pair to move. I would figure out another way.
Almost hesitant to ask if your Au Pair is going to be expected to look after your sister's kid. Am I the only that thinks 1 - 2 week visit is a long time. And OP how come you don't know the specific length of your sister's visit? |
I am single and my boyfriend(s) sleep with me on the sofa in the living room or he(they) stay in their own home when i have visitors who present space problems. |
I hadn’t even thought of that... 1-2 week play date? Yeah, no... |
We “asked” au pair if brother in law could have her room while
He was visiting and she was away on a vacation week. I would have been visibly annoyed if she said anything other than “of course”. I haven’t asked when she is there. Don’t know. I’d probably shift my kids rooms so they share. |
