Well checks are done from 0-21 years of age. These visits are more frequent during child's first 2 years. We check baby's growth, do immunizations, and keep track of their milestones. Usually, we do a well baby visit a few days after birth, at about two weeks old and then at least once every two months during the first six months (at about 2, 4, and 6 months old). After this, American Academy of Pediatrics is recommends to have visits scheduled at 9, 12, 15, 18, and 24 months old. As your child grows, well child check ups should be scheduled about once a year.
