Yes agree with this. Also gender (sex) reveals, when no one but the parents (and often not even them) care whether the baby is pink or blue!!
Just crack on and tell the people that matter (the ones you will turn to for support if things don't go to plan) and then everyone else as and when you feel like it/ they notice.
