Aptamil 4 Growing Up Milk 2-3 Years is enriched with key vitamins and minerals important for toddlers between the ages of 2-3 years. It provides the same nutrients as Aptamil Growing Up milk 1-2 years but is semi-skimmed rather than full-fat. This is in-line with the Department of Health recommendations, which state that from the age of 2, toddlers who are eating a healthy, balanced diet and are growing well, can move on to semi-skimmed cows’ milk.
