Ages 9 to 24 Months. Add water. Eating cereal & other products. Calcium for growing bones. Your baby is growing in so many ways! Getting bigger and stronger, and learning new things every day. As babies grow, their nutritional needs change too. For example, the amount of calcium babies need doubles by the time they reach age one. Cereals and other foods alone may not provide all the calcium a baby needs during this time of rapid growth. Similac 2 has been specially designed to help meet the nutritional requirements of older babies and toddlers. Similac 2 provides calcium to help support developing bones. Similac2 is fortified with iron, which is important for brain development. Best of all, it's from the makers of Similac infant formulas! Helping to bridge the nutritional gaps between what older babies will eat and what they really need.
