When Is the Best Time for a 3D Ultrasound? A Week-by-Week Guide
The best time for a 3D ultrasound is usually between 26 and 30 weeks. That's when most babies have enough fat under the skin for full cheeks and clear facial features, but still have room to move. Earlier sessions have their own magic, though, so the right week depends on what you want to see.
Here's what a 3D ultrasound looks like at each stage, and which session at Mother Goose fits each one.
3D Ultrasound at 14 to 17 Weeks: First Look and Gender
At 14 weeks your baby is small enough to fit on the screen all at once, so you can watch the whole body kick, stretch and wiggle. Facial features are still developing and look more delicate than chubby.
This is also when you can find out boy or girl. Gender determination at Mother Goose starts at 14 weeks with The Character Reveal ($125), which is why so many parents book an early gender ultrasound as their first 3D session.

3D Ultrasound at 18 to 25 Weeks: Features Take Shape
Between 18 and 25 weeks, your baby's nose, lips and fingers become easier to make out, and you'll often catch hiccups, yawns and thumb-sucking in 4D. Baby is still lean, so faces look slimmer than they will in the third trimester.
The Narrative ($135) is built for this window and includes gender determination or confirmation. It's a great choice if you want to find out boy or girl together with family in the room.
3D Ultrasound at 26 to 30 Weeks: The Sweet Spot
If your main goal is a lifelike picture of your baby's face, aim for 26 to 30 weeks. Searches for a 3D ultrasound at 28 weeks and 30 weeks are popular for a reason: baby has filled out, cheeks are round, and there's usually still enough amniotic fluid in front of the face for a clear view.
The Illustrated Chapter ($175) is our longest session at 30 minutes and is designed for 26+ weeks. It's also the best session to pair with a Hyper Realistic 8K enhancement, since 8K is created from your clearest 3D image.

3D Ultrasound After 32 Weeks: Possible, but Crowded
You can still get beautiful images after 32 weeks, but baby has less room. Faces are more likely to be tucked against the placenta, a hand or the uterine wall, and baby may already be head-down and low. If you're past 32 weeks, book sooner rather than later.
Quick Answer: Which Week Should You Book?
Want to know the gender as early as possible? 14 weeks or later.

How to Get the Clearest 3D Images
The single biggest factor you control is hydration. Drink plenty of water in the days before your visit. Good hydration supports healthy amniotic fluid levels, which helps create clearer images. Wear something cozy that allows easy access to your belly.
Baby's position, placenta location and fluid levels also affect what we can capture. Molly takes her time and works to encourage baby into a better position. If baby stays camera-shy and we can't obtain images, one complimentary return visit may be offered at the sonographer's discretion.
