Absolutely!
Infant Formulas are based on Cows Milk, Soy Milk or Goats Milk. And they are categorised as:
- 100% Whey dominant = HA Formulas
- Whey dominant = most Birth-6mth Formulas / Infant Formulas / Step 1 Formulas
- Casein dominant = From 6mth Formulas / Progress Formulas / Step 2 Formulas or Toddler Formulas
Cow's milk, Goat's Milk, Soy Milk and all other milk besides human Breastmilk, was never intended for human infants. Each mammal species produces a milk composition ideal for it's own particular species. Therefore, the composition of Whey proteins to Casein proteins in Cow's milk or Goats milk (and every other milk) will be different to breastmilk. The nutritional content (vitamins, minerals and enzymes) of other milk will also be vastly different to breastmilk, and will lacks many key nutrients present in breastmilk, which is vital for the development of human babies.
It is actually dangerous to feed any fresh milk that is not breastmilk, to human babies, as it is not only completely unsuitable for a human baby's gut but it also does not support the vital growth and development of human babies. Other than breastmilk, any fresh milk (meaning unmodified and unfortified milk) must not to be given to infants, and not to be given to older babies as a food until after at least after 12 months of age, or older if possible. All milk sources for Formulas must first be modified in both protein composition, as well as nutritional composition, with the goal of becoming as close to breastmilk as possible.
