As of this week my parents in law have taken in a refugee (through a charity but there vetting process is not great tbh) into their home. However me and my partner are now very uncomfortable about leaving our 19 month old over night. In the day she is never left alone but she sleeps in her own room at night and this is what bothers us. We feel this leaves our baby really vulnerable because they have a large house, don't use monitors and rely on hearing her in the mornings (which we tested this past weekend when we stayed, they dont hear her till she is full balling - another thing we're not happy with now). We are now in the position of telling them they cant have her overnight without us, but we dont want this to stop them offering out there space rooms. But it's a complete stranger we know nothing about and we wouldn't be there. Are we being unreasonable?
