The Average Length of Newborn

by | Newborn

It is incredible to look at a baby and see it grow into a human being. But sometimes, it can be terrifying and overwhelming for the parents to look at their children and see them growing so fast.

We all know that a baby grows fast. If you see a baby and visit them one week later, you will see them more chunky, big, and taller. Hence, it is true that newborn babies grow fast, but there is a predictable level of their growth during the first year.

Hence, here you will see different charts that can easily track your newborn baby’s length.

What is the average length of a newborn?

If you are a mom-to-be or parents and you are wondering what the average length of a newborn baby is, then you have come to the right place. Most healthy and full-term babies are 20 inches (51 cm). However, the normal range of healthy babies born is about 18 inches that is approx. 46 cm to 22 inches or 56 cm. So, if your baby is lying between these numbers, it is normal.

Average baby sizes through the first year:

Some standard numbers that World Health Organization has published show how much a baby grows in the first year after birth. Usually, babies grow about 0.5 to 1 inch each month after birth to 6 months. After six months, babies grow about 3/8 inches, approximately 1 cm each month.

You can quickly know the length and weight of your baby from the regular check. The doctor measures the length and the weight of the baby and makes a proper progress chart where he adds their height every time you visit them.

What is WHO’s growth chart for babies:

WHO, or World’s Health Organization, published a chart showing average infant growth. WHO took this observation for the children in six countries, including the United States of America.

The babies typically grow in length by about 50% in the first year of their birth. Hence, the growth chart of babies by WHO is presented below with the average lengths of both male and female babies.

What does it mean if the baby is small or large?

When a baby is born, the doctor tells several things, including the length and weight of the baby. Typically, full-term babies are around 2.5 kgs to 4.5 kgs. But if your baby is more than 4.5 kg, they are larger than usual. However, if your baby is less than 2.5 kg, they are considered smaller than average.

Now, if you experience these things, you don’t have to worry about them. There are different reasons why this might happen. There are genetic factors, a mother’s health, and sometimes it can be due to medical conditions. But mostly, it is considered normal, and there is nothing to worry about until your healthcare provider does not give you the correct information.

How to Understand the Growth of Babies?

Some parents want to learn everything about their babies. So, the growth chart is the perfect thing that helps the parents and healthcare professionals keep track of a baby’s growth.

Growth charts track a baby’s length, weight, and head circumference. So, every time you go to your doctor, they will measure all of these things and keep a record.

Every baby is different from others and comes in various shapes and sizes. When you see a growth chart, you will see the word “percentile.” Many people get confused by this word, but this is how babies are measured. The percentile lines have different percentages like 5%, 10%, 25%, 50%, 75%, 90% and 95%.

So, if the baby’s weight follows the 50th percentile line, then this means your baby, out of 100 average babies of their age, half or 50 will be bigger than them, and 50 will be smaller. Likewise, if your baby is on the 75th percentile line, she is bigger than the 75 children out of 100 and smaller or shorter than 25 children. Hence, it is essential to know that all babies grow differently. As long s your baby is healthy and responsive, there is nothing that you need to worry about.

How much should we feed a newborn baby?

One of the most common queries that new parents have is how much they should feed their newborn babies and how often. The best answer to this question is whenever your child might be hungry. There are various signs through which you can understand when your baby is hungry. They will put their hand in their mouth, cry, stick their tongue out, and a few other things. However, there are a few guidelines that you can follow when it comes to feeding your baby.

Most newborn wants food every 2 to 3 hours, and on average, they can drink about 1.5 to 3 ounces of milk every 2 to 3 hours. However, this amount can increase as your baby grows. When your baby is about 2 months old, they can drink about 4 to 5 ounces of milk every 3 to 4 hours. When your baby hits the mark of 4 months, they can drink 4 to 6 ounces of milk every feeding session. In their 6th month, your baby may drink 6 to 8 ounces 4 to 5 times daily.

Baby’s Age Amount of Feed Times of the Day
Newborn 1.5 to 3 oz Every 2 to 3 hrs.
2 months old 4 to 5 oz Every 3 to 4 hrs.
4 months old 4 to 6 oz Each feeding session
6 months old 6 to 8 oz 4 to 5 times a day

How much should a breastfed baby eat?

As we have discussed above, the feeding pattern of each baby is different. You should feed your baby whenever they are hungry. Thus let your baby guide you instead of the clock. According to the American Academy of Pediatrics (AAP), breastfed babies should eat as long as they want and as long as they feel hungry. According to the research and observation, it is seen that a newborn baby who breastfeeds eats every 2 to 3 hours—a newborn breastfeeding baby drinks at least 8 to 12 times a day.

Sometimes, there are scenarios when your baby does not want to drink, such as when they’re not feeling well or sleeping. But in such cases, you must feed your baby and ensure that your baby has a minimum of 8 feeding sessions within 24 hours.

Now you might be thinking about how long a mother should nurse their baby. So, there is no perfect timing for how long you should nurse your baby. There are different times for different people. But mostly, it is seen that a mother should nurse their baby for at least 20 to 30 minutes.

It is also easy to figure out when your baby is done nursing and when it’s time to end the session. When your baby stops sucking, or the speed of their sucking is slowed, it might be a sign that they are complete, and you can stop feeding them.

Another thing that mothers need to keep in mind when they are feeding their baby is that sometimes their little angels might want to nurse nonstop. This is called cluster feeding, a burst of feeding, and your baby doesn’t want to stop feeding. This happens when your baby is in the growth spurts phase. For you, it might feel like you are nursing and feeding your baby the whole day, but that is what your baby needs at that time. But the good news is that this phase lasts for a day or two.

How much should a formula-fed baby eat?

If your baby is not someone who is breastfeeding, then you might be feeding him formula milk. Now you might be thinking, how much should I feed him the formula milk? Again, you should give your baby no defined amount of formula milk, and the different number works for different babies.

The formula milk your baby will need depends on their age, weight, and appetite. Even this might change because a baby’s appetite changes daily, so you might need to alter the feed accordingly.

However, a rule of thumb can help you figure out the right amount of formula-fed for your baby. If your baby is 6 months and has not yet started taking solids, then you can give them 2 to 2 and a half ounces of formula per pound of body weight in 24 hours. This means if your baby is 10 pounds, they can have 20 to 25 ounces of formula fed daily.

As your baby grows, their needs will also grow, and they will need more food compared to the beginning. Mentioned below is a general idea that can help you in bottle feeding your baby.

In the first few weeks, you need to give your baby about 1 to 3 ounces of formula fed every 3 to 4 hours. Even if your baby sleeps, you must ensure they take their feed correctly.

When your baby hits 1 month, they will need more food, approximately 4 ounces every 4 hours. In the 6-month phase, they will eat about 24 to 36 ounces of feed in the span of 4 to 5 feedings per day. But all of this is just an approx., each baby is different, and their needs are also different. So, ensure you are giving your baby the food according to their needs.

What is the length of a premature baby?

After learning about the length of a full-term baby, let’s have a look at the length of a baby who might be premature. Premature birth or a premature baby occurs before the beginning of the 37th week of the pregnancy. There can be different types of premature babies depending on the week of gestation they are born in.

If your baby is premature, then the following might be the length of the boys:

Gestational Age Length
40 weeks 20 inches
35 weeks 18.1 inches
32 weeks 16.5 inches
28 weeks 14.4 inches
24 weeks 12.2 inches

For girls:

Gestational Age Length
40 weeks 12.6 inches
35 weeks 17.7 inches
32 weeks 16.5 inches
28 weeks 14.1 inches
24 weeks 12.6 inches

Why tracking the length of the babies is essential?

The weight and length of a baby is the indicator of the baby’s health. The weight is the more proper way to assess the baby’s health. If your baby’s weight is correct, it shows they have the perfect digestive system and are growing healthy. Whereas genes determine the length of the baby, and if there is a problem in height, it is more towards that they have inherited it from their parents.

However, it is vital that the doctors and healthcare professionals track and record your baby’s length and weight every time you take it to them. The growth chart helps and is evidence of a child’s health and allows the doctor to know if your baby is growing correctly or not.

What is the average birth weight and length?

As mentioned above, the average length of a newborn is about 19 to 20 inches, whereas if we talk about the weight, then the average weight of a newborn is about 5 pounds to 8 pounds.

What is an unhealthy birth weight?

If your baby’s weight is less than 5.5 pounds or more than 8.8 pounds, it might be considered unhealthy. However, there are some conditions in which this can also be a healthy weight. It all depends on your baby’s health.

Does a small baby mean my baby will be short?

If your baby was born small compared to other babies, then there is a chance that your baby might remain a small child. However, it does not mean they are going to be a short-sighted person. If your baby’s growth hormone works appropriately, they might grow in height and won’t be a small person.

Conclusion:

Babies are the cutest little creature in the world; however, everything related to them is very sensitive to their parents. Thus, most parents have many questions and queries about their length and the amount of food they should eat. Hence, we hope this article helped you are cleared out
