My sister in law is coming to the UK from overseas to spend the last ten weeks of her pregnancy. She will be having the child her as an overseas patient as she does not fulfill the criteria for NHS care (paying for NHS treatment). My parents have a flat she can stay the entire time but she will be on her own mainly. I spoke to my brother today and was told she was coming straight to us from the airport. No is that ok? Or how long can you accommodate her for?. I made my excuses and got off the phone. I have discussed with my DH and have told my brother that she can stay in my house for 2 weeks but not for the entire time. She will be welcome to stay ad-hoc for a few days here and there if she wants. I have had no response. Is this reasonable?
