Infant Development:
Infants develop reflexes that are controlled by the lower brain centers and help them respond to some of the stimuli in the environment. They develop motor skills including gross motor skills and fine motor skills. Gross motor skills are those that involve the large muscle groups of the body. Fine motor skills involve the smaller groups of the body such as fingers and lips. Some motor milestones that babies experience are: sitting up on their own, rolling over, crawling, and then walking on their own around 12-14 months. The overall development of motor skills results from inputs of genes, maturation, and the babies environment. In addition to being able to move around on their own, babies start to develop sensation and perception. The 5 senses really start to develop and grow. The babies body proportions are changing as well. Growth during infancy until age 2 is very rapid and even doubles the birth weight by about 5 months of age.

Adolescent Development:
Not much happens physically during adolescence. After the child's second birthday growth slows down to about 2 inches a year until they hit the adolescent growth spurt that is caused by changes in hormones. Girls usually begin their growth spurt around age 9 or 10. Usually between ages 10-16 girls will start their menstrual flow or their period. Boys hit their growth spurt about 2 years after girls. Puberty begins in the early teen years for both boys and girls where many physical changes occur.

Adulthood:
Once the child has been through puberty they are mostly fully physically developed. After puberty there is not much more growth. Some issues related to adulthood or physical maturation include, but are not limited to: pregnancy, STDs, keeping up with healthy nutrition and exercise, eating disorders, and obesity.
