A baby's digestive system needs to adjust to the new environment during the first two years of life. A baby may experience discomfort as a result of this natural process, including colic, excessive crying, and constipation. Nestle Lactogen 3 is a spray-dried Follow-Up formula for older babies who are not breastfed or bottle-fed after 12 months (exclusively top-fed). For advice, kindly contact a healthcare provider. Nestle creates infant nutrition products that are supported by cutting-edge research and science.
