Between the ages of 7 and 12 years, your child is in a phase often referred to as middle childhood. During this time, he is growing rapidly, changing before your eyes and mastering his physical skills. Although every child is different and develops at his own pace, you can have some idea of what to expect concerning his physical development.
Appearance and Puberty
In middle childhood, your child is slimmer than she was in preschool. This is because her body’s composition is changing. Her legs may appear long because the lower half of her body is growing faster than the upper half. Her permanent teeth are beginning to come in, as well. She may also begin puberty and have budding breasts. The American Academy of Pediatrics states that on average, girls start puberty around 10 years of age and boys start a year after that. However, every child is different, and she may start puberty early or late.
Growth
According to the Department of Psychology at the University of Kansas, your child will grow about 2 to 3 inches and gain 5 pounds each year during middle childhood. His growth is steady, and he might be very flexible because his ligaments are still attaching to his bones. Girls are slightly taller than boys until about 9 years of age, when boys become taller.
Skills
Your child’s large motor skills are improving as she becomes better at hopping, running, jumping and throwing a ball. Her fine motor skills are being refined, as well, and you may notice that her writing is more legible. The American Academy of Pediatrics states that at age 9, your child can learn more complex tasks, such as sewing or building a model. She can also handle basic chores, such as keeping her room clean, drying dishes and putting away clothes.
Encouraging Development
North Carolina University Cooperative Extension states that your child may have trouble balancing high energy and quiet activities during middle childhood. To promote his physical development, you can encourage a balance of these activities. Let him choose things that he enjoys doing. The American Academy of Pediatrics adds that too many sedentary activities can impair his bone growth, so encourage him to be active so his bones can grow dense and strong.
Concerns
Keep in mind that every child is different, and yours may not be the same size or have the same skills as other kids her age. This does not necessarily indicate a problem, especially because physical development is affected by many factors and growth spurts vary according to each child. Your child’s doctor will examine her development at regular checkups, but talk to him if you are concerned about your child’s height, weight or physical skills.
