How to Prepare for Your 3D/4D Ultrasound in Houston: 7 Pro Tips

A 3D or 4D ultrasound is one of the most exciting parts of pregnancy — and a few simple steps can make your baby’s pictures even clearer. Whether you're coming in for a gender reveal, 3D session, or HD Live scan, here’s how to prepare for your appointment at Baby Bliss Ultrasound Houston to get the best possible images — Serving the Greater Houston area.

1. Hydrate Well for 2–3 Days Before Your Appointment

Hydration is the #1 factor in image clarity.

When you drink plenty of water, it helps increase the amniotic fluid around your baby, which creates clearer visuals during your 3D/4D scan.

Tips:

• Drink 80-100 ounces of water daily for 2–3 days before your appointment

• Sip consistently throughout the day

• Hydration the day of helps, but hydration before is even more important

Good fluid = sharper baby images.

2. Eat a Small Snack Before Your Appointment

A little movement makes your ultrasound more exciting and can help baby get into a good position.

Try eating:

• Fruit

• A granola bar

• Juice

• A light snack 10–15 minutes before your appointment

This wakes baby just enough to show off kicks, yawns, stretches, or even smiles.

3. Wear Comfortable Clothing

You’ll be lying comfortably on the scanning bed, so choose something easy to lift around your belly.

Examples:

• A loose top

• Leggings

• A maternity dress

• Two-piece outfits (easier than dresses that need lifting)

Comfort helps you relax — and relaxed moms get better scans!

4. Try Not to Let Baby Nap Right Before

If possible, avoid long naps right before your appointment.
Awake or lightly active babies give:

• Better expressions

• More movement

• Better chances for good facial views

If baby’s completely asleep, we can still scan — they just may be cozy and curled!

5. Choose the Right Time in Pregnancy

For the clearest 3D/4D and HD Live images, timing matters:

Best time:

• 26–32 weeks for full-face images

• 28–32 weeks for the best HD Live (iLive) detail

• 14–16 weeks if coming for gender reveal

We can scan outside these ranges, but fluid, position, and space make a difference.

6. Bring Anyone You Want to Share the Experience With

At Baby Bliss Ultrasound Houston, you’re welcome to bring family or friends to enjoy the moment with you.
We make it cozy, calm, and memorable for everyone.

7. Relax — We Adjust Settings for Each Mom

Every pregnancy is different.
We adjust your ultrasound machine settings based on:

• Baby’s position

• Mom’s body type

• Placenta placement

• Fluid levels

• Gestational age

This ensures you get the best, clearest photos possible.

If baby isn’t cooperating, don’t worry — we always try multiple angles and techniques to help them move.
