Is gender disappointment really a thing?

I’m in a rainbow baby group on the book, and I just read this post that has me in complete shock. To sum the post up: this woman experienced 2 late term miscarriages with baby girls. She is pregnant again and just found out she is having a baby boy. She goes into details saying that she is no longer looking forward to having her baby, Is disconnected from the baby, and is in a super depression over it.

I get being disappointed over a gender (when we did ours a year ago you can see the disappointment on my husband’s face for 30 seconds and then he gets happy).

I feel that there is something else (maybe some mental issues)going on with the OP on the book. Maybe I’m just being mean… I’m not sure. My husband and I tried for 10+ years to have our 7 month old daughter. I have had multiple miscarriages and even had a stillborn. I feel that if someone has had pregnancy loss/fertility issues that a healthy and happy baby would be a blessing no matter what the gender is.

I guess my whole point is has anyone else experienced anything like this before?
