Dreading the Holidays, or How to Cope with MIL

Yes, I am dreading the Holidays. We fly home for Christmas early tomorrow morning, and as much as I love my family, I am really not looking forward visiting. Especially the in-laws, my mother-in-law (MIL) specifically. She knows our struggles with infertility, and yet it's like she has selective amnesia. Last Christmas was difficult because I had a miscarriage the previous spring and my 'due date' would have been around late November/early December, so I was especially sensitive. MIL kept bringing up the baby of Husband's friend from back home, like in the car on the way to church, at Christmas dinner. Ugh! The last time she brought it up I had to be nasty and mention that the friend never wanted children (according to my Darling Husband) and is appeasing his wife (did I mention the baby is, well, ugly). Other times MIL brings up adoption. It's difficult to discuss these topics, so I try not to say much. She really would love a grandchild, but I don't know if we'll be able to provide one, biological or adopted. This year I'm feeling stronger so hopefully it will go better and I won't let her harping get under my skin.
