Global Perspectives on Child Growth

Table of Contents


Child growth and development can be broadly defined as a typical pattern of changes that occur over time from infancy to adolescence to allow children to understand and interact with the world around them. Kids’ bodies change as they get older, and some of those changes are their height and weight going up. Your hair grows, your teeth come in, come out, and come back in, and then you hit puberty. It’s all a part of growing up.


How normal is it?


The first year of life is a time of amazing change. Babies usually triple their birth weight and grow 10 inches (25 centimeters) in length.
New parents may be shocked if their child doesn’t continue to grow so quickly after the first year, when so much growth takes place. But no kid grows at the same speed as an infant. A baby’s length doesn’t grow as fast after age 1. After age 2, most kids keep growing taller at a steady rate of about 2½ inches (6 centimeters) per year until they are teenagers.
During this time of childhood, though, no child grows at a perfectly steady rate. In most kids, short periods of slower growth are followed by bigger “growth spurts” every few weeks or months. In fact, kids grow a little faster in the spring than at other times of the year.
Girls usually go through a big growth spurt between the ages of 8 and 13 and boys between 10 and 15 years old. Teenage years last between 2 and 5 years. During this growth spurt, sexual development takes place. Hair starts to grow in the crotch area and underarms, sex organs grow and develop, and for girls, periods begin.
Girls will no longer be going through puberty by the time they are 15 years old, and boys will be 16 or 17 years old. This means that they are physically mature.


Going to the doctor’s office


From the time they are babies, kids will go to the doctor for monthly checkups. On a growth chart, the doctor will write down the child’s height and weight and match them to those of other kids the same age. If a child is growing at the right rate or there might be a problem, this useful tool can help the doctor figure it out.


What can parents do to help for child growth?


There are some things you can do to make sure your child grows and develops properly. For the sake of their health and well-being, kids need
• Get enough rest: The way a kid sleeps changes with age and for each child. But most kids need between 10 and 12 hours of sleep each night. Sleep helps bodies grow by giving them the rest they need.
• Healthy food: Kids can grow as tall as they can if they eat a healthy, well-balanced diet full of minerals and vitamins they need.
Getting regular exercise: Many kids are overweight, so parents should make sure their kids get regular exercise. Any fun exercise that gets kids moving, like biking, camping, inline skating, sports, or anything else, is good for their health and fitness and will help them keep a healthy weight.


How to Talk to Kids About Growing Up


As kids, they grow and develop in different ways. Kids aren’t all the same height, just like adults. In general, girls reach puberty before boys do, but some girls may be later than their peers in getting their first period or breasts developing. All of this happens all the time.
Don’t compare how much brothers or other kids have grown. Calling attention to something like a child’s height will only make them feel bad about their size. Tell your kids to be okay with how they change and grow. Tell them that kids develop and grow at different rates and that those who are behind the curve usually catch up in the end.
Kids have a lot of questions about growth, from why their teeth fall out to things that are uncomfortable or embarrassing, like how their breasts grow or why they sweat. To help kids understand the many changes they’re going through, be honest when they ask you questions and even start conversations about growth. This will help them be okay with the changes.
If you don’t want to talk about these things with your kids, they might feel bad about the changes they’re going through and be less likely to tell you about their problems.
Kids who are short are often made fun of by their peers and may need help dealing with it. Help by making your child feel good about their own self-worth. Like, it might be tough for a little boy to get on the football team. But going after other things, like soccer or tennis, might help him feel better about what he can do and himself. Keep the lines of conversation open and try to understand how your child feels.
Another way to make your child feel better is to get them involved in things that aren’t about their height or weight. There are also unique skills and traits that you should be proud of, like being good at music or reading a lot.


What Should I Do If I Believe There’s a Bug?


Some parents worry about how their child is growing and changing. It can be comforting to know that most kids who are short or behind schedule are healthy and fine. Kids who grow up with parents who are shorter tend to be shorter too, though not all kids develop at the same rate.
Talk to your doctor if you are worried. The doctor can look at your child, ask about your family background, and, if necessary, order tests to see if your child has a health problem that is stopping them from growing. If your kid has a growth problem, the doctor may want to check on their growth more often or send them to a pediatric endocrinologist.


Learn about the different steps of a child’s development


Knowing the changes your child will go through as they grow and develop is an important part of being a parent. As kids go through a series of growth stages, they may face a number of problems that are pretty common.
Even though no two children are exactly the same, there are ideas about how people grow and develop that everyone agrees on. Not only do children look different, they also act and behave differently, as well as having different social and mental traits. During different stages of growth, kids also change how they connect with others and how they react to their surroundings. These changes usually happen in a logical order, but the speed at which they happen varies from child to child.
Parents can give their child the care and attention they need if they know how their child grows and changes over time.


Stages of a child’s growth


There are four clear steps of a child’s growth and development, which are:
• Infant Development (baby and Baby): A baby will lose between 5 and 10 percent of their birth weight right after they are born. A baby’s weight should double between 4 and 6 months after birth. After that, it will slow down during the second half of their first year.
• Development of Toddlers (Preschool Years): Toddlers will gain about five pounds each year from ages 1 to 5.
• Childhood Development (Middle School Years): Your child will continue to grow steadily, but around age 9, when they start puberty, they will have a big growth spurt.
• Teenage Development (Teen Years): A child’s growth will usually be at its fastest in their mid- to late-teens, when their bones are fully formed.
Changes in a child’s growth will also cause changes in their food needs. Children as young as babies need more calories than kids in preschool or middle school. As a kid gets older, their nutritional needs will rise again.
For a child’s health and growth, as well as for their brain development, good diet is very important. Kids might not have enough energy or feel tired if they don’t eat enough during the day.
Growth charts are a way to track a child’s physical development.
Every child grows at their own speed. Kids come in a lot of different healthy shapes and sizes. A child’s height and weight are affected by many things, including their genes, gender, diet, level of physical exercise, health problems, surroundings, and hormones. Many of these things can be very different from one family to the next.
Doctors look at a child’s growth charts along with information about their health, surroundings, and family history. The doctor might also ask: ₧ Is the child hitting other growth milestones?
Are there any other signs that a kid isn’t well?
Is the child’s parent or brother a certain height and weight?
Was the baby born before it was due?
Has the child hit puberty earlier or later than usual?


Is there a single growth chart for all child growth?


Not at all. There are different growth charts for boys and girls because they grow at different rates and in different ways. From birth to 36 months, one set of charts is used for kids. Kids and teens between the ages of 2 and 20 use a different set. You can also use different growth charts for kids who have certain diseases, like Down syndrome, or who were born early.


What Could Be a Sign of Trouble for child growth?


If you or your child’s doctor keep an eye on growth charts, you might be able to spot any problems with growth. When a child’s weight or height percentile changes from what it’s been following, that’s a pattern to keep an eye on. Say a child’s height and weight have both been in the 60th percentile until they are 5 years old. Then, at age 6, the child’s height drops to the 30th percentile, which could be a sign of a growth problem because it is not following his or her normal growth pattern. But just because the percentiles change doesn’t always mean something is wrong. There are times when growth rates will vary more between children, which is normal. At these times, many children may have changes in their growth percentiles. This happens a lot when kids are babies and when they are teenagers.
Should a child’s growth in height not match what their parents thought it would be, they should talk to their doctor.
• If the body mass index is too low or too high (BMI <5% or >85%), not normal.
While growth charts can be helpful, it’s important to remember that they don’t tell you everything you need to know about your child’s health or progress. Meet with your child’s doctor if you have any questions or worries about their growth or growth charts.
From elementary school to pre-teenage years, there is still a wide range of what is “normal” for kids in terms of height, weight, and shape.
Every year, kids grow about 2.5 inches (6 to 7 centimeters) taller. Which is a pretty steady rate. Kids gain about 4 to 7 pounds (2 to 3 kg) of weight every year until they hit puberty.
Kids also start to care about how they look and how fast they’re growing at this age. Some girls may worry that they are “too big,” especially those who are growing quickly. Boys often feel bad when they are too short.
It’s more important for your child to be healthy than to “look” a certain way. Kids can’t change the genes that make them taller or change the time when they hit puberty. What they can do to reach their full potential, though, is change bad eating habits and get more exercise.
Regular checkups with your doctor will include measures of your child. These will then be put on a standard growth chart so that you can see how they change over time and see how they compare to other kids the same age and gender.


Getting Your child to Grow


Normal growth, which is supported by a healthy diet, enough sleep, and regular exercise, is one of the best ways to tell if a child is healthy generally.
Your child’s growth trend is mostly set by their genes. Kids won’t grow taller if you force them to eat more or get more vitamins, minerals, or other nutrients. In fact, it could make them gain weight.
Kids learn to accept themselves when you accept them as they are.
Teenage years
Both boys and girls go through big changes during puberty, which is also known as sexual growth. Different people start going through the physical changes of puberty at very different ages.
During these changes caused by hormones, both boys and girls go through growth spurts that make them physically mature teens as their bodies mature.

Girls’ breast growth, which is often the first sign of puberty, can start at any age between 8 and 13. As girls reach puberty, the following things happen: • Their breasts start to grow and their hips round out.
• The rate of height growth starts to speed up.
• Pubic hair starts to show up about 6 to 12 months after breast growth starts. In about 15% of girls, pubic hair will grow before breast hair does.
• The lips and clitoris get bigger, as well as the uterus and vagina.
• There is a lot of pubic hair, and the breasts are getting bigger.
• By the time a person is 12 years old, having reached puberty, their rate of height growth has reached its peak.
• Periods usually start after a girl has hit her peak height growth rate, which is usually around 12.5 years old.
Teenage girls generally gain an extra one to two inches (2.5 to 5 centimeters) of height once their periods start. They hit their full adult height by 14 or 15 years old, though this can be younger or older based on when puberty started.
Between the ages of 10 and 16, most boys start to change physically as they hit puberty. Between the ages of 12 and 15, they tend to grow the fastest. It takes boys about two years longer than girls to reach their peak height. Most boys stop growing around age 16, but their muscles will still get bigger.


Other things that happen during puberty in boys are

• The penis and testicles get bigger
• Hair grows in the pubic area first, then underarms and face

• The voice gets deeper and may crack or break occasionally
• The throat cartilage, or Adam’s apple, gets bigger

• The testicles start to make sperm
