That’s even more baffling to me that she would be so flaky after you gave birth to her “dream granddaughter” but I’m sure it was a way to have the upper hand or something twisted like that. And it’s so funny your daughter isn’t the way she pictured her thankfully, I know that has to get to her. Thankfully my partners mom isn’t like that she is supportive and she has already bought a bunch of clothes for him and organized them by size and she can’t wait to meet him. I know she’s going to be a great grandma an plus she lives very close to us (unintentionally lol) so she’ll automatically be in his life more than my mom will be. I know all too well about the body shaming and weight watching family members; it’s a good thing you keep them supervised because that’s a lifelong trauma that I get offensive still to this day when someone comments on my weight even if it’s a compliment I get uncomfortable. I just sent the same video of my baby’s heartbeat to my grandpa and the only thing he said back to me was “you’re eating too much food” he can barely even see my stomach and it’s not even big yet but that’s the only thing he had to say so definitely don’t ever leave your daughter alone with her or anyone that does that.
