Toddler Growth Spurts: Age, Symptoms And Timeline

Toddler growth spurts may occur between the ages of one and three years. Toddlers grow a few inches and gain a few pounds each year of toddlerhood (1). Growth spurts are periods when a toddler has sudden and intense growth. As a result, they may appear hungrier and need more food than usual to meet the extra energy needs due to rapid growth.

Additional supplements or treatments are not required during growth spurts unless the toddler has some nutritional deficiencies. The growth rate is periodically reviewed during pediatric visits using growth charts. Doctors may prescribe supplements if needed.

Read on to learn more about the signs of toddler growth spurts, ways to estimate height, and reasons for short stature.

When Do Toddlers Grow?

A child grows in phases, and it is not a continuous process. You may observe a sudden increase in growth and then a stable phase. A toddler’s growth milestones may include the following stages (2).

  • Year one: In their first year of life, a baby may gain half a pound per month and grow taller by four to five inches.
  • Year two: Your toddler may gain three to four pounds and grow taller by three to four inches in the second year. 
  • Year three: Your toddler may grow two to three inches taller and gain four to six pounds of weight in the third year.
Your toddler may grow two to three inches taller in the third year.

After the completion of three years, the rapid growth may decrease, and they may have growth spurts again only during puberty. However, the height and weight of your child will continue to increase gradually. Usually, they may gain nearly six pounds and grow two inches taller per year during the school ages.

What Are The Signs Of Toddler Growth Spurts?

The following signs are often associated with growth spurts in toddlers.

  • Increased hunger
  • Sleeping more number of hours at a time
Excessive sleep is a sign of growth spurts in toddlers
  • Increase in height and weight

Some toddlers may complain of leg pain and often wake up from sleep during growth spurts. Children usually outgrow this phase without specific signs and symptoms.

How Tall Would A Toddler Be?

When it comes to a child’s height, genetics plays a significant role (3). According to the American Academy of Pediatrics, tall parents usually have tall children, and short parents usually have short children. “Those are the realities of genetics,” adds the academy (4).

The average height of a toddler is mostly calculated based on the parent’s height rather than comparing it with a similar age group. You can use the mid-parental height formula to determine the projected adult height of your toddler in inches (5).

  • Girls: [(Father’s height in inches – 5) + Mother’s height in inches] divided by 2
  • Boys: [(Father’s height in inches + 5) + Mother’s height in inches] divided by 2

The formula represents the projected height, and there could be variations since a toddler’s adult height depends on other factors, as well.

Besides genetics, the following factors may cause changes in height (6).

  • Nutrition: Toddlers with malnutrition may not achieve their natural growth rate.
Nutritious diet plays a key role in achieving normal growth
  • Medical problems: Thyroid abnormalities, chromosomal anomalies, kidney problems, gastrointestinal diseases, such as celiac disease and other malabsorption disorders, heart defects, and food allergies may reduce the growth rate in toddlers.
  • Sleep: Inadequate sleep may hinder toddlers’ growth and development since the growth hormone is mainly released during sleep.
  • Psychosocial growth failure: Stress and poor emotional health of a child may result in a slower growth rate.

Toddlers may begin to grow after the correction of nutritional deficiencies, treatment of diseases, and when they are moved to a supportive and safe environment. However, genetic factors cannot be changed. 

Jennifer, a mom of triplets shares how each one is growing taller at their own speed, “My children share a birth date and were cohabitants in my womb for almost 7 months. Today as they were playing after school I slowed them down to document the vast difference in their height. Based on the rate at which the boys’ pants have been ‘shrinking’ I knew we were in some sort of a growth spurt–especially R [my son]. The difference in his height and K’s [my daughter’s] is huge. One minute apart in birth–half a head apart in height (i).”

What Might Cause A Toddler To Have A Short Stature?

The primary cause of short stature is usually inherited genes from the parents (7). Growth delay and medical conditions could be the other causes. Most healthy toddlers grow at a regular rate and enter puberty at an average age. They may reach an estimated height at puberty. Medications, supplements, or treatments to increase height are not recommended for children.

Some children may have short stature due to growth delay. Although they had normal growth during the early months of life, some babies may fall below the average growth between six months and two years. Some may grow after this age and catch up to adult height. It is more common in boys than girls. This is a natural process, and treatments are not required.

If short stature is due to a deficiency of growth hormone, a pediatrician may prescribe growth hormone injections based on the growth chart and parental height.

A toddler’s growth spurts are a natural part of their development. During the first three years of life, there are several growth surges. Toddler growth spurts result in various physical, behavioral, and cognitive changes, including increased eating, sleep disturbances, increased height and weight, and so on. Each toddler goes through a growth spurt at a different period and rate. Despite their development spurts, some toddlers may be shorter than others. A child’s height is determined by genetics, nutrition, maturation, and underlying medical issues, among other factors.

Key Pointers

  • Toddler growth spurts happen during the first three years of their lives.
  • The growth spurts are characterized by the child’s height, weight, appetite, or sleeping more hours at a stretch.
  • Nutritional deficiencies, sleep, other medical conditions may also impact the child’s height.

Growth spurts are a normal part of a baby’s development. Learn how to recognize the signs and when they usually occur.
