For when to take vitamins also depends on the structure of the diet. Breakfast is usually eaten in a monotonous structure, you can let your child take a tablet after breakfast or at dinner. 3-6 year olds can choose to take a tablet at bedtime. 3 year olds can be crushed and put in their usual water and let your baby drink it. When you stay up late, you can also take vitamins, not too much, as long as the body is not deficient in vitamins do not take, the body itself will take vitamins and trace elements through the diet as needed.
