Long story so I'll keep it as short as possible.
DH's brother split from his Ex in October last year - they have a son similar in age to our daughter. Son lives with his Mum about 180 miles from us. BIL doesn't see much of son, is now with a new girl and that's a whole other story.
I have asked my nephew's mum if he'd like to stay with us in the holidays, to which she said yes. I am pleased but now concerned that BIL will be mad I set this up without speaking to him first.
What would you have done/do? I really want to see nephew and so does DD.
