Even the pickiest kids can't resist fruit smoothies, which are naturally sweet and can be an excellent way to sneak nutrition into their diet. Beware of store-bought smoothies, however, which are usually full of added sugar. These end up carrying as many calories as a full meal (for a toddler). You might as well be giving them a milkshake [source: Bohn].
If you make the smoothies at home with fresh fruit such as bananas and strawberries, plain yogurt and low-fat milk, it'll be a healthy source of calcium and protein.
HINT: If your child isn't getting enough fiber or protein in his or her diet, add powder supplements to the smoothie.
