Girls on the first ultrasound asked about the sex ? (couldn't help it) they seemed like a girl, but that's not for sure. Did we match with the first ultrasound? Or is it better not to believe 100%, waiting for 2 )))) as husbands were told the baby's sex? I want to come up with something really interesting. We'll definitely know right under the New Year!
