Enfamil Infant formula is tailored to meet the nutritional needs of babies zero through 12 months. It has a dual prebiotics blend designed to help support a baby’s own natural defenses, as well as choline, DHA, iron and vitamin D. As your baby grows and develops, he reaches new and more complex milestones. These milestones are driven by cognitive, motor, social and communication areas of the brain. Enfamil Infant has DHA, a fatty acid recommended by experts and important for infant brain development. As your baby starts crawling and becoming more active, immune system support is important. Prebiotics feed the good bacteria found naturally in the digestive tract where 70% of your infant's immune system is located. Emerging science suggest prebiotics may support your baby's developing immune system. Enfamil Infant has a dual prebiotic blend designed to work throughout the digestive tract for more complete support compared to our previous formula.
