The Internet is a funny thing. You can type in “autism” and pretty much any other word, and you’ll find people claiming a link between the two. Cow milk? Yep. Same with microwaves, cell phones, computers, televisions, formula, and everything else.
Either way, we’ve switched over to goat milk from cow milk. It’s insanely more expensive (topping $12/gallon) than cow milk, but it does seem to set better on his stomach. His diaper was filled with a rainbow of coloured droppings over the week he was on cow milk, and it seems to be a lot more consistant with goat milk.
I still think it’s cheaper than formula, at least.
