I'm coming at this from an intercultural perspective, but my own experience is that in many countriescertainly in the United Statesyou can buy either branded formula (Enfamil, Similac etc.) or "store brands" like the Parent's Choice that you can buy at Walmart. There is basically no difference in terms of quality or what is in them, but the generic ones are much cheaper. I've asked and it appears that generic formulas don't seem to be available in the UK? Why is this? Wouldn't this be a good thing for parents? I also feel that generics would be more ethical, somehow.
