When Does Baby’s Nose Fully Develop

When we talk about a baby’s nose, parents also ask when does baby’s nose fully develop?

Your baby’s nose starts to grow in the mother’s womb in the fifth week after conception, while in the seventh week of pregnancy, nasal pits, cartilage, and nasal bones are formed and continue to develop throughout the pregnancy period. Nose cartilage will turn into a bone around the second and third years of a baby’s life.

Their small noses can become swollen immediately after giving birth, but this is temporary and there are no more significant problems. The size of a newborn’s head makes it difficult for doctors to assess how well his or her nasal passages are functioning at birth.

At six months after birth, your baby breathes completely through the nose because the diameter of the nose doubles and thus gives the baby the opportunity to breathe freely.

In the first 3 years of life, the nose continues to grow, the bones will start to harden and continue to harden until puberty.

During puberty, the child’s nose will continue to grow. For girls, the time the nose will stop growing is usually 15 -16 years old, while for the boys is 17-19 years. With age, your bones, muscles, and skin in your body change, including the shape and size of your nose.

So, actually, our noses never stop growing. 

When does baby’s nose return to its normal shape?

In most cases, a baby’s nasal bridge will look almost straight after about two to four weeks from birth until the nose returns to normal.

But if there has been trauma during delivery or prolonged pressure on the bridge of the nose then it can take up to two months for it to recover. 

Sometimes during childbirth, the baby’s nose can be pressed, as well as the whole body, as it passes through the uterus. This is not a big danger because the baby can withstand this kind of pressure without any problems. It is normal for the nose to be a little wavy in shape and a little flat.

After delivery, it is important that the baby’s nose is kept clean and moist in order to prevent dryness and cracking. The nostrils should both be gently cleaned twice a day in order to prevent infection.

It is also recommended that ointments are not applied to the newborn’s nose unless instructed by the healthcare provider, as this may irritate the delicate skin of a newborn.

Why does my newborn baby sneeze so much?

The reasons why your baby sneezes so much can be various. When the little one sneezes, the baby frees the airways, frees the nostril that is stuck to the nose, the fibers from the blanket can tickle the baby’s nose, hair, dust, pollen are just some of the reasons why babies sneeze. 

By sneezing, babies expel small particles from the nose and thus clean the nose. A small piece of cotton wool soaked in saline is enough to clear the baby’s airways and stop sneezing.

Make sure the room the baby is staying in is fresh. You can do the following: Ventilate the room where the baby is staying, do not smoke in the room where the baby is, and keep the baby away from allergen sources. If your baby still sneezes often, you should consult the baby’s pediatrician.

However, there are also things you can try, to help your baby clean its little nose from all the dust and dirt. If the baby has a cold and her or his nose is blocked, drip one to two drops of saline into each nostril to cause sneezing, so the baby cleans its airways and throws out secretions from the nose.

If the general condition of the baby is good, you should not go to the pediatrician, but in case of fever, constant baby crying, cold nose, or anything that makes you worried, be sure to contact the child’s pediatrician.

What is the deal with the 3D Ultrasound?

New moms are overwhelmed with questions. They often ask, when does baby’s nose fully develop, as well as what is the deal with getting the 3D ultrasound. 

Going to your first ultrasound is a time full of joy because you are going to see your baby for the first time.  But at this point, the joy of parenthood can turn into shock. The picture of your baby is not what you expected.

In all that confusion, parents have a lot of questions for the doctor: why my baby has such a big nose, and why somebody parts are overemphasized?

You were expecting a picture of your child painted by Michelangelo, but it is a 3D ultrasound that is not near perfect.

The ultrasound tries to see your baby in your stomach by sending sound waves in three planes at a certain angle, so you can see your child’s whole body. A number of surfaces must be bounced off by sound waves in order to create an image.

To clearly understand why some baby’s features look disorder during your 3D ultrasound, we need to understand the whole sound wave process more thoroughly. 

Problems seem to be occurring due to the size of a baby, which is very small, and its surface that is smooth and soft, thus there are not a lot of surfaces for sound waves to be bounced off. 

So, when you see a picture of your baby with a big nose, don’t panic, your newborn is certainly beautiful and most likely has a small nose. It’s just an ultrasound trying to play with young parents. Ultrasound is completely safe for both your baby and the mother, so there’s no room for fear.


When babies are born, they have small features. Small hands, legs, toes, and fingers, as well as the cute little button on their faces that represents their nose. However, these things are not meant to stay small forever, even though they are unbelievably cute. 

Therefore, parents tend to ask, when does baby’s nose fully develop. Well, there are a few stages. Right at the beginning of the pregnancy, at the fifth week after conception, the baby’s nose should start to develop.

A bit later, around the 7th week of pregnancy, nose cartilage, nasal pits, and bones are formed and continue to develop throughout the pregnancy. 

During the time of childhood as well as the period of puberty, the child’s nose will continue to develop along with the nose bridge. It will probably stop developing at the age of 16 for girls, and 19 for boys.

However, the human nose never stops growing, so until we are alive, our noses will grow.
