Just to add, there have been huge recent almost unfathomable changes in what we ingest, and 'from scratch', as in our lives! I don't think in the history of humanity feeding babies high sugary fructose drinks instead of human milk was the norm, but that is what I was fed for instance, from babyhood. And I am not alone, I take it. Yes, and here I am today with insulin resistance to die for.
Feeding babies cow's milk instead of human milk too, and soy, and... well the list goes on. This idea we have that we can genuinely improve on Nature (whatever that means to you) and not stuff it all up, by sticking on a lab coat, and calling it 'a formula', for instance, and then, for good business - convince as many in the world that it is an improvement and that your babies will be better off for it.
