Gender disappointment

So my husband sister is pregnant with girl (14 weeks) and she found out tonight what she is having.

Well she and her boyfriend are going thru gender disappointment.They we’re hoping for boy and even before gender reveal she told me she is hoping for boy (her older brother had son when she was younger,her second brother my husband we have two sons).

I had gender disappointment but I got over it and I love my boys more than anything in this world but I know how she is feeling but idk should I send her text that I know how she is feeling and that is okay to feel like that.

Because honestly no one approached me when I was going thru that or should I just text nothing l?
