when's the best time to get a 3d/4d ultrasound?

Depends on how much you want to spend. I'm getting one Saturday at 17 weeks and I'll probably get 1 or 2 more lol I like seeing my baby

between 28 and 32 weeks

I have mine schedules at 28 weeks... with my 2 boys I had it at 28 and 29 weeks

between 28 and 34 weeks

I got mine at 28 weeks
