Pregnancy is a remarkable journey filled with excitement and anticipation. One of the most magical moments for expectant parents is seeing their baby in the womb. At Take A Peek, we understand how important this experience is. That’s why we offer a range of scans, including early pregnancy scans, gender reveals, and 4D scans. With over 70 years of combined NHS experience and a CQC rating of GOOD, we provide professional, reassuring care in a family-friendly environment.
The best time to have a 4D scan in pregnancy is between 28 and 33 weeks. This window allows us to check your baby’s growth and capture stunning, detailed images of your little one. In this post, I’ll explain why this timing is ideal, what you can expect during your scan, and how we support you throughout your pregnancy journey.
Why 28-33 Weeks is the Ideal Time for a 4D Scan
Choosing the right time for a 4D scan is crucial to get the best possible images and accurate information about your baby’s development. Between 28 and 32 weeks, your baby has developed enough fat under the skin to show clear facial features, but there is still enough room in the womb for movement. This balance makes it the perfect time to capture those precious moments.
At this stage, we can also assess your baby’s growth and wellbeing. We measure key parameters such as head circumference, abdominal circumference, and femur length to ensure your baby is growing as expected. This information can provide reassurance and help detect any potential concerns early.
Before 28 weeks: Your baby is smaller and less developed, so images may be less clear.
After 33 weeks: Your baby may be too large or positioned in a way that makes scanning difficult. But we often get lovely images even at 35 weeks, its all dependent on position

What to Expect During Your 4D Scan Appointment
When you arrive at our clinic, you’ll be welcomed by our friendly and experienced team. We pride ourselves on creating a warm, family-friendly atmosphere where you can feel comfortable and relaxed.
The scan itself is a non-invasive ultrasound procedure. You will lie comfortably while a sonographer applies a special gel to your abdomen and moves a probe to capture images of your baby. The 4D technology allows you to see real-time, moving images of your baby’s face and body.
During the scan, you can expect:
Clear, detailed images of your baby’s features and movements
Opportunity to see your baby yawn, stretch, or even smile
Confirmation of your baby’s position and growth measurements
A chance to ask questions and receive professional advice
We also offer gender reveal options if you want to find out your baby’s sex during the scan. Many parents enjoy sharing this special moment with family and friends.

Early Pregnancy Scans and Additional Services
While the 28-33 week window is best for 4D scans, we also provide early pregnancy scans to confirm your pregnancy and check for viability. These scans are usually done between 6 and 12 weeks and can provide reassurance during the early stages.
In addition to baby scans, Take A Peek offers a full range of NIPT blood tests. These non-invasive prenatal tests screen for common chromosomal conditions and provide valuable information about your baby’s health. We also provide private pelvic scans for individuals seeking fertility or general health checks.
Our comprehensive services mean you can access all the care you need in one place, with a team you can trust.
