Every year Ds and I spend Christmas with my Mum, Step-Dad, 2 sisters, BIL and as many extras and can fit in the house!
Since my ds was born the guest list has also included my Aunt (my Dad's Sister). She and my mum didn't speak for a decade and were forced to reconcile when ds was born.
For the last couple of years, my aunt has volunteered with a charity on Christmas day so has come and spent a couple of hours with us in the morning then gone off to do whatever it is she's signed up for.
My mum is not speaking to her at the moment and it's just occurred to me that there is no chance that mum is going to invite her for Christmas (even if the invitation is declined) and it's going to cause real awkwardness with them both!
Any suggestions on how to deal with it/them?
