"Low-fat soy milk and rice milk contain low levels of fat and protein. If these products are used parents must be sure children are getting adequate fat and protein from other dietary sources. Infants get adequate fat and protein from breast milk or infant formula. Full-fat soy milk is generally recommended for young children. Breastfeeding a child during the second year of life helps assure adequate fat and protein intake as well." ¹ Please note there is no such thing as "full-fat" soy milk as there is full-fat cow milk. The highest amounts of fat would be found in "regular" soy milk, one that is not labeled low-fat.
