Baby’s Only® Organic Premium Infant Formula should only be mixed with water according to label instructions. Use of other milk or liquids will not only increase the caloric content of the formula but may also inappropriately increase other nutrients such as protein, fat, carbohydrates, vitamins, and minerals. This has the potential to result in an excess renal solute load (the byproducts of digestion filtered through the kidneys for elimination in the urine), which could harm the kidneys. Only water should be used to mix the formula, unless specifically instructed to use a liquid other than water as recommended by the child’s healthcare provider.
