Cereals are the best solid food provided to baby as a daily meal. Cereals are fully supplemented with iron, vitamins and minerals for baby's healthy growth and development. Nutritional cereals like grain cereals are made from grains such as rice, barley and oat. Commercial baby cereals are specially processed into fine flakes, then precooked and dehydrated so they're easy to eat and digest. These refined grains are readily available in the market. One can also prepare grain cereals at home by grinding up the grains into powder with the use of grinder or food processor. This powder then becomes your baby cereals. Additionally there are many things you may add to the cereals that will give an iron boost such as formula, breast milk, wheat germ, and brewer's yeast. Many commercial baby cereals are whole grain and are made with whole grain flour. However there is nothing more pure and whole as buying whole grains and making them into 100% pure baby cereal.
