I wasn't going to find out with Kameron, but as soon as the u/sound started, he had legs wide open and the wand thingo was right on that spot so it was a bit hard to miss iykwim. We didn't tell any family though.
With Lachlan we wanted to know in case we had to buy girl stuff, so it is good cause you can get organised with the right sort of stuff for your gender, but it is a con cause you don't get the IT'S A GIRL or IT'S A BOY after delivery cause you already know. Unless the u/sound is wrong which has happened, then it truly would be a surprise.
