How Much Does Diet Impact Growth?
"Genes are the most important factor, but you can't reach your genetic potential if you're not adequately nourished," explains Dr. Rauch. If she is eating a balanced diet, your child probably doesn't need a multivitamin. However, the American Academy of Pediatrics recommends that all infants, children, and adolescents get a daily dose of 400 IU of vitamin D, which is essential for healthy growth. Since it's hard to get enough vitamin D from food alone, your child will probably need to take a daily supplement soon after she is born, unless she gets at least 34 ounces of D-fortified formula per day.
