The really crazy thing I’ve seen is non-medical 3D ultrasound pics of your baby. This is the most stupid thing ever. Let’s rattle around the baby’s brain at 40 Khz because we are too impatient to wait for the kid to pop out.
I have no idea how these people got their hands on that equipment.
I guess I am old school. My idea of a gender reveal party is um birth! The procedure is when the baby arrives the gender is revealed. Father hands out cigars....although that may be a little too old school nowadays.
