Raw milk?

Sadie

So I'm not ready to start giving my son milk. And I didn't plan on doing it anyway as I don't believe cows milk is good for toddlers. However my aunt gives her children raw cows milk and goats milk that she gets from a credible farm. The good fatty content in it is good for the brain which is removed when it's pasteurized. However what are you guys opinions on raw milk? I know some totally disagree due to the idea of it not being "clean" but other than that?
