If the mom wants the gender to be a total surprise until she gives birth, is it okay for her to keep it a total secret from everyone else as well?

If the dad/dads family wants to find out early, should they be allowed to access that information?

I see both sides of the argument, but I feel like it’s okay if she doesn’t want the secret getting out before birth. A lot of people are bad at keeping secrets, and chances are everybody would end up knowing by the time the baby was born.

Personally, I would feel hurt if I wanted the gender to be a surprise and everyone else found out anyways.
