Healthy infants should be seen by their doctor often during the first year of life. Preventive health care visits (also called well-child visits) typically take place within a few days after birth or by 2 weeks of age and at 1, 2, 4, 6, and 9 months of age. During these visits, the doctor uses age-specific guidelines to monitor the infant's growth and development Physical Growth of Infants and Children Physical growth refers to an increase in body size (length or height and weight) and in the size of organs.

At these visits, the doctor gives parents age-appropriate safety guidelines.
The following safety guidelines apply to infants from birth to age 12 months:

Do not give infants foods and objects that can cause choking or be inhaled into the lungs.
Do not use baby walkers.
Place safety latches on cabinets and cover electrical outlets.
Remain alert when watching infants in the bathtub or near a pool or any body of water and when they are learning to walk.
