Enfamil A.R. infant formula is a great supplement that allows babies to keep food down. Babies who spit up food on a regular basis do not receive the requisite amount of nutrition. Enfamil A.R. minimizes the frequency of spit up. Fortified with rice starch, there is no need to add rice cereal to this formula. In addition, the formula has the Enfamil LIPIL nutrient blend to nourish eye and brain development and strengthen immunity. Available in two forms: a ready-to-use liquid and a powder.
