Sounds like there are a lot of us with MIL issues!!
My MIL lives around 2 hours away from us, and it took her a year until she met our daughter. We were down in her town about 5 times in that year and she was always too busy to see us.
Meanwhile on FB she is always commenting on how "her" granddaughter is so beautiful and how she takes after her side of the family. She is also quick to save/steal photos from our FBs and post them on her own and say how gorgeous our DD is... and loves all the comments she gets from her friends about her.
I just don't understand how someone can want so little to do with our DD yet love the attention she gets from being her grandmother? So annoying!
I don't even refer to her as my DDs grandmother in front of her..... as far as I'm concerned she has one grandmother and that's my mum. My husband is fine with this as it upsets him too with how little effort his mum puts in. We haven't even told her we're pregnant this time.
