Why Does My Baby’s Nose Look So Big On Ultrasound?

Ultrasound visits are nervous and exciting. 

Don’t you get excited to see how your baby develops beyond the gestational sac with a heartbeat for the first time?

 Surely, your mind has images of a perfect button nose, chubby cheeks, and a sweet smile when you go for your ultrasound anatomy scan. 

Unfortunately, most ultrasounds between 18 and 22 weeks, even in 3D, do not look like that.

As an expecting parent, you’re not alone if you feel uncomfortable with the images on your screen. 

The anatomy scan has sometimes revealed a strange or creepy face to parents. Several perfectly normal reasons can explain the sonograms.

Why Does My Baby’s Nose Look So Big On Ultrasound?

If you go for an ultrasound, you might be surprised to see a baby with a big nose.

You’re not the only expecting parents watching the screen and seeing a big nose.

That’s not to say there’s anything wrong with a big nose. Ultrasounds tend to distort babies’ noses.

The following information will help you understand what ultrasounds, your baby’s nose, and other things have to do with pregnancy.

1. How Does 3d Ultrasound Work?

Some background information on 3D ultrasounds is needed to understand why certain features of the baby are shown distorted.

The images created by 3D ultrasound work on sound waves and technology that can read those sound waves.

The 3D ultrasound captured the images of infants for a short duration, and most of it was two-dimensional.

Rather than capturing full-body images, the two-dimensional images could only capture surface images.

As a result, ultrasound technicians had to chase the baby around the womb until they found them.

Three 90 degree planes capture using 3D ultrasound. This device sends sound waves and then listens to them while bouncing back.

As a result of those waves aimed at different angles, the device can create a full-body image of the baby.

If there is a problem with the shape and size of some of your baby’s features, the sound waves don’t bounce off of them as much.

It’s not uncommon for people to worry about having babies with big noses when a particular feature enlarges.

You may not be getting an exact image because of this distortion, which is what parents want; however, it will improve over time.

Seeing your baby this way also allows you to connect with her more strongly, which is wonderful. 

2. ​Growth Scans Don’t Always Reveal All

​During an ultrasound, we can see our baby’s condition inside the womb.

A 3D scan now gives you a view that your parents couldn’t see when they were pregnant with you.

Three-dimensional ultrasound is a technology that shows you what your baby might look like and how they are doing inside the womb.

The benefit of a 3D or 4D scan for most moms is that they can see their baby in the womb.

We see nothing but gray matter in 2D scans, which is excellent but disappointing.

Even the specialist cannot tell us where our baby is without pointing it out.

With 2D ultrasound, you’ll be able to see through your baby and see its heart beating.

The 3D image of your baby that you get from an ultrasound is more realistic.

You can see an accurate image of your growing baby inside your womb with a 3D scan of your scanned image of your little one.

Four-dimensional (3D) refers to space, but the fourth dimension refers to time.

The baby inside your womb is moving and doing things. Your baby might be sucking her fingers or grimacing.

The fluid in your baby’s stomach has made their skin wrinkly and slightly swollen.

Therefore, if the 3D scan indicates that your child’s nose is large, don’t worry too much.

Your baby’s face is mashed up against your placenta.

The uterine wall or placenta can even appear to have an incredibly thick set of lips because of the pressure on the lips.

3. The Inside of Your Womb

​Imagine what your baby’s lips looked like inside your womb if their noses were as large as yours.

The size of the kind can freak you out. Nevertheless, your child had the cutest lips ever – not thick, not heavy, just the right size and shape.

​3D scans can show if your baby resembles you or your spouse more.

Do not look at your scan if you are concerned about your baby’s size or whether your baby will have a flat nose when they are born.

It is very likely that the baby will look more like you, your husband, or your closest relatives.

Your baby may not inherit your big nose even if you and your husband have big honkers, but inherit your siblings and his sibling’s small cute noses.

Having an idea of your baby’s characteristics will depend on knowing what characteristics your relatives and your husband’s family have in common.

A good example is your infant might inherit the big nose from the same big nosy people on your husband’s side.

A baby with a dominant family ancestry has a better chance of inheriting it.

4. The Teeth, Nose, Eyes, And Ears Of Your Baby

​You will surely leave more than just a nose to your baby. You or your significant other likely inherited her eyes, ears, and smile.

Baby’s features will usually be a mix of yours and theirs.

You’ll have the smoothest skin you’ve ever felt after six weeks of waiting if your baby looks like a hairy baboon after birth.

If you have a baby who looks like a shrunken head of Peru, just wait a month, and you’ll see how handsome he is.

Wait until your baby grows up, and you’ll see what cute ears she’ll have.

A baby’s face changes over time, so it won’t be a problem if you don’t like how your baby looks now; they will look fantastic.

Editorial pick: What Is The Best Time For 4D Ultrasound Scan?


Now, you know why my baby’s nose looks so big on ultrasound? 

​The number of buttons on your baby’s nose isn’t as significant as they entirely beak.

Regardless of how your child looks, you will still love her regardless of how she looks. 

But being able to see your baby once she’s born is a completely different experience from having an ultrasound.

The 3D scan of your baby shows you the accurate picture only when they have a huge nose, so keep waiting and be happy!
