Ages & Stages: Growth and Development

How to tell if your child is growing properly

What Is Growth?

From the moment parents greet their newborn, they watch the baby’s progress eagerly, anticipating every inch of growth and each new developmental milestone along the way. How can they tell if their child is growing properly?

Physical growth refers to increases in height and weight and other physical changes that occur as a child matures. Hair grows; teeth come in, come out, and come in again; eventually, puberty hits. It’s all part of the growth process.

What’s Normal?

The first year of life is a time of astonishing change during which babies, on average, grow 10 inches in length and triple their birth weights.

Given all the growth that occurs, new parents might be surprised when their child doesn’t continue to grow as rapidly after the first year. No child continues the rate of growth experienced during infancy. After age 1, a baby’s growth in length slows considerably, and by 2, growth in height usually continues at a fairly steady rate of approximately 2½ inches per year until adolescence.

Children do not grow at a perfectly steady rate throughout childhood, however. Weeks or months of slightly slower growth usually alternate with mini “growth spurts.” Kids actually tend to grow faster in the spring than at other times of the year.

A major growth spurt occurs at puberty, usually between ages 8 and 13 in girls and 10 to 15 in boys. Puberty lasts about two to five years.

By the time girls reach 15 and boys reach 16 or 17, the growth associated with puberty will have ended for most and they will have reached physical maturity.

At the Doctor’s Office

Beginning in infancy, kids should visit a doctor for regular checkups, during which their heights and weights are recorded and compared on a growth chart with those of other kids the same age. The chart is a valuable tool that can help the doctor determine whether a child is growing at an appropriate rate or whether there might be problems.

What Parents Can Do

You can do a few things to help ensure that your child grows and develops normally. Critical to kids’ overall health and wellness are:

Enough rest: Sleep patterns vary by age and individual child, but most kids need an average of 10 to 12 hours of sleep per night. Sleep gives children’s bodies the rest they need to continue growing properly.

Proper nutrition: A balanced diet full of essential vitamins and minerals will help kids reach their full growth potential.

Adequate exercise: Because obesity is a growing problem, parents should make sure their kids exercise regularly and eat healthy. Bicycling, hiking, in-line skating, sports or any enjoyable activity that motivates kids to move will promote good health and fitness and help them maintain a healthy weight.

Talking to Kids About Growth

Kids differ in growth and development during childhood—like adults, some kids are taller or shorter. Generally, girls hit puberty earlier than boys, although some lag behind their peers in physical development and the onset of menstruation. All of this is usually completely normal.

Try to avoid comparing growth among siblings or other children. Drawing attention to height, for example, will only make a child feel self-conscious about his or her size.

Encourage kids to accept their own growth and development.

Explain that some kids grow and develop at different rates—and late bloomers usually catch up eventually.

Kids have many questions about growth, from why their teeth fall out to difficult or potentially embarrassing topics such as physical development or perspiration. Answer questions honestly and even initiate conversations about growth to help kids understand the many changes they’re experiencing. This will help them accept the changes positively.

Kids who are short are often teased by peers and may need help coping. You can help by supporting your child’s self-esteem. For example, although it might be difficult for a small boy to make the football team, emphasizing alternatives, such as soccer or tennis, may make him feel better about himself and what he can do. A small teen might have concerns about dating, driving and participating in sports. It’s important to try to understand your child’s feelings and to keep the lines of communication open.

Another way to boost your child’s mood is to encourage activities that don’t focus on height or weight. Emphasize special talents or individual qualities, such as musical aptitude or a love of literature.

If You Suspect a Problem

Some parents worry about their children’s growth and development; it can be reassuring to know that most kids who are short or delayed in development are healthy and normal. For example, shorter parents tend to have shorter children and not all kids develop at the same rate.

If you have concerns, the first step is to consult your doctor, who can thoroughly evaluate your child and your family history and, if necessary, order tests to see if there’s a medical condition affecting growth. The doctor may choose to monitor your child’s growth more frequently on a growth chart or refer your child to a pediatric endocrinologist (a doctor specializing in growth disorders) for further evaluation.
