Okay for anybody interested in getting 3D/4D ultrasounds done for a single baby 28-29 weeks is a great time to go. For multiples I'd say closer to 24-25 weeks would be the more ideal time since they have a bit more room to move and there's more space between the babies. I just got mine done at 28 weeks 4 days, same time as with my singleton and for him it was perfect not that great with twins. We still got some great shots but not as many or as great as it could've been. When looking for an elective ultrasound it'd be nice if they'd make this note so you're able to take full advantage of this awesome experience.
