Toddlers continue to grow by a few inches and a few pounds each year of toddlerhood (1).
Some toddlers may have a sudden increase in growth and often appear hungry during growth spurts since their bodies need extra energy.
All healthy toddlers grow at a normal pace to achieve the estimated adult height later in life. There is no requirement for treatment or supplementation to enhance growth unless there are some significant nutritional deficiencies. Your toddler’s pediatrician may periodically review your toddler’s growth rate against a growth chart.
Read this post to know more about the signs of growth spurts, estimated height, and causes of short stature of a toddler.
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 timeline 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.
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 Spurt?
The following signs are often associated with growth spurts in toddlers.
- Increased hunger
- Sleeping more number of hours at a time
- 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.
- 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 t
- 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.
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. 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.
Growth spurts in toddlers are part of normal growth. Provide your little one with proper nourishment, good sleep, and adequate physical activity to facilitate this growing phase. Do not worry if your toddler’s height is not the same as their peers’; each child grows at their own pace. If you have any concerns about your toddler’s growth spurt, discuss it with a pediatrician.
