Best time to have a 3D/4D ultrasound?

Baylee • Second time mommy! 2 year old little boy, wonderful fiancé and another one on the way 😍
What is everyone's opinion on when to get a 3D ultrasound? I'm 13 weeks now and my next appointment is at 16 weeks to find out gender! I've had friends wait until around 28-32 weeks to get them done! Anyone have recommendations?
