Babies under 6 months need about 3 mg of zinc every day, 5 mg every day for 7- 12 months, and about 1- 10 years old. The daily zinc supplement for children is 0.6~ 1.5 mg/kg body weight. In addition to paying attention to the amount and time of zinc supplementation, the most important thing for growing babies is to scientifically arrange three meals a day, that is, to eat more vegetables, fruits and potatoes, and often eat milk, beans and their products.
