One of the most dynamic and quick stages of a person’s life is the growth and development of toddlers between the ages of two and six1. Children experience incredible changes in their bodies as well as in their minds, emotions, social skills, language abilities, and ability to solve problems1. Knowing what to prepare for during this crucial phase enables parents and other caregivers to support healthy development, spot problem areas early, and offer caring support that improves wellbeing.

Growth and development occurs in five major stages2:

  • Infancy (from birth to age 1)
  • Toddler (ages 1 to 5)
  • Childhood (ages 6 to 11):
  • Teenage or adolescent (ages 12 to 18)
  • Adulthood

Growth in childhood is described as an irreversible, continuous increase in size, whereas development is defined as an improvement in motor skills2. Environmental, dietary, and genetic variables play a major role.

Physical growth (height, weight) and brain development including skills and abilities are the fundamental components of normal growth and development of toddler. This evolution takes place in several domains:

normal growth and development of toddler

  • Physical growth: Changes in body size, muscle development, coordination
  • Cognitive growth: Thinking, reasoning, memory, problem-solving
  • Language development: Understanding, using words and sentences
  • Social-emotional development: Interacting with others, expressing feelings
  • Motor skills development: Fine and gross motor coordination

Early growth and development of toddlers is more than just physical growth. Neural connections are formed during the first six years of life, laying the groundwork for future learning, behavior and health3.

Toddler stages of growth and development: Year by year4

Parents during this stage will notice dramatic shifts:

Age group (years)

Physical Milestones

Language Milestones

Cognitive Milestones

Social Milestones

2 – 3Runs, climbs, kicks ball, stack blocksUses 2-3 word phrases, follow simple commands, uses gesturesHolds things, begins pretend playNotices emotions
3 – 4Jumps, pedals tricycle, draws circleSpeaks in sentences, asks questions, names actionsIdentifies shapes, draws circle, avoids touching hot objectPlays with other children
4 – 6Catches ball, skips, hops on one foot, buttons clothes independentlySays sentences with 3-4 words, Tells stories,  uses rhymesNames colors, counts numbers, writes a few lettersComforts others, follows rules, does simple chores

Normal Growth and Development of Toddlers: What’s Typical?

Understanding typical development is important because every child grows at their own pace. While milestones give guidelines, there’s a broad range of normal1. Growth patterns are influenced by genetics, nutrition, environmental, health status and emotional support.

Typical growth patterns:

  • Height and weight:

Toddlers grow about 2-3 inches in height and gain approximately 4 to 6 pounds per year after age two5.

  • Brain development

Neural connections related to language, attention, and executive skills are actively forming1.

  • Motor skills:

Gross and fine motor milestones are continually refined, enabling more complex physical tasks1.

Using growth charts: Toddler boy and girl growth charts6:

These are essential tools for tracking a child’s physical development over time. These charts plot height, weight, and body mass index (BMI) against age and sex specific percentiles to determine how a child compares to typical growth patterns.

Boys and girls grow differently physiologically, especially in areas like muscle mass and body composition7. This is why pediatricians use separate toddler growth chart for boys and girls.

Uses of growth chart8

  • Help track weigh –for-age, height-for-age and BMI-for-age
  • Useful for identifying undergrowth (e.g. <5th percentile) or overweight risks
  • Offers insight into normal growth and development of toddlers

If a child fails significantly off established growth patterns, further assessment for nutrition or health concerns is recommended.

Nutrition and sleep fuels growth:

Consistent good sleep and nutrition are important for normal growth and development of toddlers.

After the age of two, growth often slows down a little, which causes appetite to decline9. When a child just eats white bread or no veggies, parents are frequently concerned. The toddler boy and girl growth chart guidelines state that “food jags” (eating only one type of food) are typically temporary as long as the child is following their curve. In situations where picky eating or reduced appetite makes it difficult to meet daily nutritional needs, parents may consider nutritionally fortified beverages as a supportive addition to a balanced diet. Complan Nutrigro is a milk-based beverage for children which offers 33 vital nutrients and minerals and high-quality, easily absorbed protein than other drinks. It helps in child growth and development by making sure they get enough protein.

Including naps, a child between the ages of two and six need about 10 to 13 hours of sleep10. Growth hormone is secreted during sleep, which makes it essential for the growth and development of toddler’s physical systems11.

Role of Parents in encouraging growth:

Role of Parents in encouraging growth

“Scaffolding” is the most effective way to support all toddler stages of growth and development. This strategy provides them with enough help to do tasks that they are still unable to complete on their own and progressively lowering that help as they gain confidence12. Other ways:

  • Read aloud: It is the most effective method for enhancing cognitive development and expanding the language abilities of toddlers13.
  • Avoid screen: Restricting screen time is important, with the WHO advising that children under the age of 5 should have less than one hour of screen related activities each day14.
  • Outdoor play: It is important for growth and development of toddler to engage in outdoor activities so they can achieve physical milestones14.

Red flags of growth and development4

“Red flags” are indicators that a child may require extra help when monitoring the growth and development of toddler. Regression, which occurs when a child abruptly loses a skill they previously learned, like speaking or using bathroom, is one of the main causes of concern. Other signs could be unable to jump by the age of 3, unable to speak simple words by 4, lack of interest in playing with other kids. It’s advised to consult a doctor as soon as possible if your child isn’t meeting these typical toddler stages of growth and development.

Conclusion

The growth and development of toddlers lays the foundation for lifelong health, learning and behavior. Understanding milestones, using toddler boy and girl growth chart and providing proper nutrition with adequate sleep and parental support help ensure normal growth and development of toddler. Early attention to delays allows proper care and better outcome for every child.
