Grandparents reaction???

Just want to know if anyone else has experienced this...

First-time soon-to-be grandmother (DH's mom) said some not-so-nice things when we told her we were expecting, such as "I was getting sick of waiting for a grandchild" and "I saw all my friends becoming grandmothers and thought 'why not me'"...

What she doesn't know is that it took us 2.5 very long and heartbreaking years to get pregnant, and only with the help of IVF.

Honestly, since it's the first grandchild, I expected much more "joy" as opposed to this passive aggression. Both DH and I felt the sting of her words and even with subsequent conversations, have been disappointed and upset with her behavior. She's opted for a nagging and judgmental tone instead of a caring and concerned grandmother role...

Just can't understand why she would want to taint it??

Any psychologists out there with a diagnosis!!!?!
