Physical Development & Care of Infants

2. Physical Development Includes:
Growth in size and weight.
Increasing ability to control and coordinate in body movements
Physical development starts at a prenatal stage.

3. Head-to-Toe
Babies develop control of head and neck muscles first. Then the muscle control moves down the baby’s body.
For example, they will raise their heads to see an object before they learn to crawl and use their legs.

4. Near-to-Far
The infants development starts at the trunk of the body and moves outward.
They can simply wave their arms before they can reach and grab an object.

5. Simple-to-Complex
Babies first develop their large muscle groups such as their legs, arms, neck, and torso.
After gaining control of these muscles, they begin to learn complex tasks such as...
Controlling the head, rolling, reaching, crawling and continue through to walking.

6. Growth & Development during the First Year

11. Influences on Physical Development

A stimulating environment in which the baby has a wide variety of things to see, taste, smell, hear, and touch enhances development.
