Families searching for a gender reveal ultrasound Chantilly VA parents recommend have two choices at Baby Realz in Leesburg: find out the sex on screen during a live ultrasound reveal, or get a sealed envelope to open whenever and wherever you want. Either way, the answer comes from a studio 25 minutes from Chantilly where 27 years of OB/GYN sonography backs up every session. This guide covers both options, when to book for each, and how to plan the kind of reveal moment that actually goes the way you imagined.
Quick Takeaways

Baby Realz in Leesburg offers gender reveal ultrasound starting at 14 weeks of pregnancy. The studio gives Chantilly families two options: a live on-screen reveal where you find out together in the room, or a sealed envelope where Amy keeps the result private and hands you the answer to open later — at a party, at home, or in a way that's entirely yours to design.
Which option is right depends mostly on what kind of moment you want. Each has real advantages.
Many Chantilly families use the sealed envelope when they want to plan a party but don't want to find out in a studio — they want the big reveal surrounded by balloons, family, and confetti poppers. Others prefer the intimacy of the studio, with just the two of them, or the immediate reaction of parents and siblings in the room.
Both options are available at Baby Realz. Let the team know your preference when booking.
Chantilly families who want to know their baby's gender before 14 weeks have another option: SneakPeek DNA testing, which is available from 6 weeks of pregnancy. It works differently from ultrasound and suits a different kind of reveal.
You want the visual experience — seeing the baby's anatomy on screen as Amy identifies the sex. You want to bring family and watch live. You're far enough along (14+ weeks) and you want the reveal to feel like a real moment rather than a result in an email inbox.
You're in the first trimester and can't wait. You want to find out alone before telling anyone. You need the result weeks in advance to plan a party. You're comfortable with a text result rather than a visual experience.
Some Chantilly families do both: SneakPeek at 6 to 8 weeks to know privately, then an ultrasound gender reveal at 14 to 16 weeks as the moment they "officially" tell everyone — with the reaction on screen. The two approaches work together rather than competing.
Ultrasound gender determination works best when the baby is in a position where the anatomy is visible. That's why Baby Realz requires 14 weeks as the minimum — before that point, determining sex via ultrasound is much less reliable regardless of equipment quality or sonographer skill.
According to the American College of Obstetricians and Gynecologists, fetal sex can often be determined by ultrasound in the second trimester, with reliability improving as pregnancy progresses. The 14 to 18 week window gives families an earlier answer than waiting for the anatomy scan at 18 to 20 weeks, while still offering reliable accuracy.
A few timing notes worth knowing:
14–16 weeks: Amy performs a 2D scan first to identify gender. Some babies cooperate; some need a little coaxing. This window works well but baby position matters more. If baby isn't cooperating, a short walk and another attempt usually resolves it.
16–20 weeks: Baby is larger and more clearly defined. This tends to be a reliable window for gender determination, and it's before the anatomy scan that most OBs schedule around 18 to 20 weeks — so you get the answer early.
20+ weeks: Very reliable window for visual gender confirmation. If you're comfortable waiting, the anatomy scan timing can work, but many Chantilly families prefer the keepsake studio experience over the clinical setting for this particular moment.
For Chantilly families using the sealed envelope option, here's the most useful advice: don't underestimate the logistics.
Baby Realz is at 880 Harrison St SE, Suite 29/31 in Leesburg — a 25-minute drive from most of Chantilly via Route 50 West or the Dulles Toll Road. Parking is available at the suite.
A few things that make the visit smoother:
Drink water before you arrive. Hydration improves amniotic fluid clarity, which helps imaging. This matters especially for gender determination where a clear view of anatomy is needed.
Eat something small beforehand. A little food increases fetal activity, which can help baby move into a better position if needed.
Know your reveal preference before you walk in. Will you want the result sealed, or do you want to find out live? Tell the team when you arrive so they can set up the session accordingly.
Bring whoever you want there. Partners, parents, siblings, friends — the studio accommodates guests and the reveal is meant to be a moment worth sharing. Some families bring grandparents from both sides. Others keep it to just the two of them. Either works.
We drove from Chantilly with both sets of parents and found out together in the room. Everyone was crying — including Amy. It was not what we expected, and it was exactly what we needed.
Gender determination at 14+ weeks is one appointment. Many Chantilly families turn it into the first of two or three visits to Baby Realz across the pregnancy.
The most natural combination: gender reveal visit at 14 to 16 weeks, then a 3D/4D/HD keepsake session at 26 to 32 weeks when facial imaging is at its best. Two separate moments, two separate keepsakes. Some families also add a heartbeat animal to one of those visits — available from 10 weeks onward.

Baby Realz is at 880 Harrison St SE, Suite 29/31, Leesburg, VA 20175. From Chantilly, the drive is typically 20 to 30 minutes depending on traffic, via Route 50 West or the Dulles Toll Road and then Route 7.
Ultrasound gender determination is available at Baby Realz starting at 14 weeks of pregnancy. Before 14 weeks, ultrasound results are not reliable enough for gender determination — Baby Realz requires this minimum to protect the accuracy of your result. SneakPeek DNA testing is available from 6 weeks for earlier answers.
Yes. Amy will confirm the sex during your session and seal the result in an envelope before you leave. You can take it to a baker, a planner, or simply hand it to someone you trust to keep the secret until your reveal event. Let the studio know this is your preference when you book.
At 14 weeks, accuracy is good but somewhat dependent on baby's position. It improves as pregnancy progresses. Amy is honest about what she can and can't confirm — if baby isn't in a clear position, she'll say so and attempt to get a better view before the session ends. Accuracy improves significantly from 16 weeks onward.
Yes. The Baby Realz studio welcomes partners, parents, siblings, and friends. Many Chantilly families make the gender reveal a group experience, with grandparents from both sides in the room. Others prefer an intimate two-person reveal. Either way, the studio can accommodate your preference.
It happens occasionally. Amy uses positioning changes, a short walk, and session timing to encourage baby to move into a clearer angle. If baby truly won't cooperate, she'll be direct about it — and Baby Realz has rescan options for cases where a conclusive result wasn't possible.
SneakPeek gives you a result at 6 weeks — earlier, private, delivered digitally. Ultrasound gives you a visual experience at 14+ weeks — live, shareable, more emotionally immediate. Many Chantilly families use SneakPeek to find out privately early and then book an ultrasound session as the "official reveal" for family and friends later.
Some packages allow you to combine gender determination with keepsake imaging. However, if your primary goal is the clearest possible 3D/4D facial images, most families get the best results booking two separate visits — gender determination around 14 to 16 weeks, and keepsake imaging at 26 to 32 weeks when baby's features are more developed.
Yes. The session uses standard obstetric ultrasound technology, operated by Amy Davidson, an ARDMS-registered sonographer. The AIUM confirms no adverse biological effects from diagnostic ultrasound at standard exposure levels. Sessions are kept to appropriate lengths and are not extended beyond what's necessary.
