During the first year of life, baby’s digestive system needs to adapt to the new environment. This is a natural process that may lead to baby’s discomfort such as colic, excess crying, and constipation. Nestlé LACTOGEN 2 is a spray dried Follow-Up formula for infants after 6 months when they are not breastfed or (exclusively top fed). Please consult your healthcare professional for guidance.
