I’m heart broken.

I have PCOS and we have been trying for a while to give my daughter a sibling. She’s almost 3 and she sees a lot of her little friends getting siblings and of course Daniel Tiger just got his sister. So yesterday she had a total meltdown while with her nana wanting a baby sister. I should mention we are pregnant finally! YAY!!! I am so early in my pregnancy that we haven’t told anyone. Well my mother in law knows that I have PCOS and we have been trying and have had round after round of fertility treatments. She videoed my daughters melt down and posted it to Facebook. All of her friends are commenting on it how she needs a baby sister and my mother in law says “she’s barking up the wrong tree. She needs to talk to her mommy and daddy.” Making it out like we aren’t trying and my daughter wants this thing and we’re just like “🤷‍♀️ too bad” no! She’s completely insensitive to our situation. Which is SO crazy to me because her own daughter has a lot of medical problems and she fishes for sympathy for her ALL OF THE TIME! Now when I get on Facebook I see this video of my daughter crying and crying and it makes me so mad that A) instead of comforting her she films it for Facebook and B) she plays it off like we’re not struggling and acts like this is a personal choice. There wasn’t even a nod to my infertility, just played it off like there’s nothing wrong. Am I over reacting?
