A 4-year-old child has already undergone a period of continuous development both physically and mentally. At this stage, parents pay close attention to their child’s weight and height, as these reflect the quality of care provided over time. This article provides information on how to promote height growth for a 4-year-old child.
1. Development Process of a 4-Year-Old Child
Physical development: From the third year onward, the growth rate of a child's height starts to slow down compared to the first two years. On average, a child’s height increases by approximately 6.2 cm per year. Meanwhile, weight gain stabilizes at around 2 kg per year. At this stage, the physical development of a 4-year-old is quite noticeable, but the growth rate varies for each child depending on parental care. Notably, the height growth rate of boys differs from that of girls due to gender-related factors.
Intellectual development: Cognitive development is directly proportional to height growth. At this age, the brain develops significantly, making children more independent and creative in learning new things. Additionally, they begin to express personal emotions more openly.
Children can replicate shapes they recognize and stack blocks based on patterns they perceive. Proper nurturing during this period fosters better cognitive development, making children smarter and more adaptive.
Motor skills development: At school, children participate in physical activities that enhance their motor abilities, such as running, climbing, and throwing objects.
Motor skills in 4-year-olds manifest through the following abilities: Standing on one foot for over 5 seconds; Performing somersaults and jumping; Walking up and down stairs without adult assistance; Walking forward and backward with ease; Using spoons and chopsticks; Dressing and undressing independently…
Communication skills: At this age, children exhibit significant language development. They are curious, eager to learn, and able to communicate effectively. Their vocabulary expands, and they begin to think logically and respond to simple questions. Most 4-year-olds enjoy singing, rhyming and arranging words in sequences.
2. Growth in Height and Weight of a 4-Year-Old Child
According to the World Health Organization (WHO) guidelines, the standard weight for a 4-year-old child falls within the following ranges: boys: 15.5 - 16.5 kg and girls: 15 - 16.1 kg. To achieve these weight benchmarks, children need a balanced diet, regular physical activity, and healthy lifestyle habits such as proper sleep routines.
Height growth: The average height increase for a 4-year-old is 6 to 7 cm per year. The standard height ranges are girls: 100 - 102.7 cm and boys: 100 - 105 cm. Height differences between children are influenced by genetics, nutrition, sleep habits, and overall care.
Relationship between height and weight: According to Dr. Francisco J. Rosales, Medical Director of Abbott Nutrition Research and Development (USA), a child’s growth is not only a key indicator of health but also reflects their overall nutritional status. A well-growing child should have a proportional height-to-weight ratio appropriate for their age.To explain this, it can be based on the fact that when a child reaches the standard weight, their height can develop properly.
If a child experiences prolonged slow weight gain, they may develop nutritional deficiencies and stunted growth, leading to poor physical development. In such cases, inadequate height and weight can cause children to feel insecure about their appearance.
On the other hand, monitoring a child’s growth also helps maintain their weight within an appropriate range, reducing the risk of being overweight or obese, which can negatively affect height development. A balanced relationship between weight and height is crucial for a child's overall health. Therefore, parents must regulate their child’s weight to prevent excessive thinness or obesity, minimizing potential health risks.
3. How to Care for a 4-Year-Old Child for Optimal Growth
Scientific studies have shown that proper care significantly enhances a child's holistic development. Some essential methods to support weight and height growth include:
• Developing a nutritious meal plan: Parents should create daily or weekly meal plans that ensure sufficient nutrient intake based on recommended dietary allowances.
• Encouraging physical activity: Children should be engaged in activities such as games or interactive learning with friends. This not only helps with physical development but also teaches children about friendship and sharing.
• Teaching simple household chores
• Reading books together: Reading to children every night enhances their vocabulary and linguistic skills.
• Limiting screen time: Excessive use of televisions, computers, and mobile devices should be restricted to encourage active play and cognitive development.
• Ensuring adequate sleep: A 4-year-old child needs 10 to 13 hours of sleep per day for optimal development.
Nutrition plays a crucial role in height development. Parents should ensure their child consumes a well-balanced diet that includes proteins, carbohydrates, healthy fats, vitamins, and minerals. At this stage, fat intake should account for 30% to 40% of total daily energy to support growth.
To enhance height growth effectively, parents can incorporate protein-rich foods, calcium, vitamin D, vitamin K, and essential minerals into their child's diet. Recommended foods for height development include:
Height-boosting foods for a 4-year-old child can be selected based on their nutritional functions. These include chicken, seafood, fish, tofu, soybeans, various nuts, eggs, milk, and dairy products, as well as dark leafy green vegetables.
Parents should structure their child’s daily meals into three main meals and two snacks, incorporating fruits and fiber while limiting excessive salt, sugar, and oily foods.
Along with proper nutrition, regular physical activity is essential for healthy development. Engaging in activities such as walking, cycling, ballet, and aerobics strengthens bones and muscles while promoting a healthy lifestyle. Developing a habit of regular exercise not only helps children stay physically active but also instills an awareness of the importance of maintaining a healthy body. Additionally, physical activity supports both physical growth and cognitive development, contributing to overall well-being.
Since improving height and weight is a gradual process, parents should remain patient and consistent in providing appropriate nutrition and supplementation. When choosing dietary supplements, natural, easily absorbable options should be prioritized. Parents should avoid using multiple supplements simultaneously or frequently switching between different brands.
