Vitamins Question: My daughter is two years old, should I put her on a multivitamin or is that appropriate for only older children? - Donna A. Answer: Vitamins are supplements used when the diet doesn't contain enough of the essential nutrients needed. There is controversy as to whether anyone that has a complete diet should take them. Certain vitamins are essential for growth and development, especially during the first few years when brain development is at it's peak. At the end of the 2nd year of life, the brain is approx. two-thirds the size of an adult. If your toddler is one of those picky eaters bypassing veggies for example, you may want to supplement with a multivitamin. Remember that certain vitamins such as A D E and K are what are known as fat soluble vitamins. Because of their nature, they tend to get stored in the liver and other body tissues. Over time, this can cause side effects. ( Too much of a good thing)! If you are not sure if your child is getting enough vitamins in his diet, speak to your pediatrician. There are nutritionists that can help you decide. Also, there are numerous books that you can purchase which can help you determine whether or not your child is in need of vitamins. Remember not to expect a toddler to sit down and eat three large meals a day. You may think he eats like a bird. Get a pencil and paper and one day write down everything he eats for the day. Most days you'll find that he eats a fairly balanced diet if given a variety of foods to choose from. It's amazing that children will consume the majority of foods that their body needs. Let them choose, with your guidance of course! Dr. Betti Also see: Does Strep Throat lead to Scarlet's Fever?
