Could you tell me if infant formula were only made available by prescription would that be a good thing?

Why: Although breast feeding is best and preferred for the first year there are a number of reasons mothers end up formula feeding. Difficulty obtaining formulas in the 60's & 70"s led mothers to make their own from evaporated cow milk.The home made stuff was deficient in many nutrients but with early solid foods the kids grew up. Putting up barriers to force a parents choice is too much nanny state.
