Is this normal?

I get sad every time I see someone’s gender reveal and “it’s a girl”.

I hope I have my little girl some day. 😖 I have two boys. A two year old, and 8 week old. I’ve had two back to back miscarriages last year, and I’m sure one of them were a girl, because my son kept saying, “sissy.”

Maybe one day.

But is it normal to be sad? Like it’s kinda funny in a way... why would I be sad? Why can’t I just be happy for them?
