$8.95 Shipping - AFTERPAY | HUMM | LAYBUY


Do I need to make an appointment?
Yes, you will need to make an appointment at our Cairns studio. Our Book Now feature can help you select your preferred date, time and package. Walk-ins are difficult to accomodate due to our workload.

Do I need a referral?

No! Our service is strictly non-diagnostic and is designed purely as a unique bonding opportunity. Before visiting, you must have had at least one diagnostic scan (either dating, nuchal or morphology) to ensure you have a viable pregnancy before visiting.

What is the optimal time of the pregnancy to have a 3D/4D Ultrasound?
If you plan on having only one 3D/4D ultrasound examination, we would recommend having the ultrasound performed between the 30th and 38th week of the pregnancy. However, excellent images of your baby can be obtained anytime. Due to us specialising in this field and after many years of perfecting this industry,  we have found that the best stages are between 15-25 weeks(for gender and body images) and 30-38 weeks (for best face images and interaction, seeing smiles, and responding to voices). In between these times,  babies are often breech or transverse, which can result in you not being able to see your babys face. Many Oh Baby clients visit more than once - it's great to watch baby grow and develop into their own little person!

Do I need a full bladder?
No, however we do need you to be WELL hydrated as this will giver you clearer images. We encourage our clients to do their best to drink close to 2 litres of water a day in the 1-2 week lead up to their appointment.

Can I bring my family and friends?
Yes. In fact, we encourage our clients to invite family and friends to attend the elective 4D ultrasound session. This is a joyous and wonderful experience, one that can be shared with your family and loved ones. (Please enquire at your chosen studio location about how many guests you can bring)

Are you able to tell the sex of the baby?
Yes, we offer guaranteed gender determination from 15 weeks. We can't, however, guarantee that the baby will cooperate during your session. Certain factors beyond our control, such as body tissue content, developmental stage and fetal position all affect the ability to determine the gender of the foetus, and Oh Baby can provide no warranty or guarantee the accuracy of any such determination. If in the unlikely event your baby is born and Oh Baby was actually wrong about gender, you will be offered a full refund as part of our gender scan guarantee.


Will I always get a beautiful picture of my baby?
Usually, but not always. Sometimes if the baby is persistently looking face down, i.e. towards your spine it may be difficult to see the baby's face. If this happens, a repeat scan on another day (at no extra charge) will usually succeed because the baby has turned to a more favorable position. We make no promises that the images will be similar to those you might have seen elsewhere or even from our clinic, or that we can always meet everyone's expectations. Every baby scans differently, depending on its gestational age, position, amount of fluid, and mother's condition. We promise to make every effort to obtain the best possible images of whatever parts of the baby that can be seen.
