Cows are often pregnant while they are milked, so dairy milk contains hormones like insulin-like growth factor-1 (IGF-1), estrogens, and progestins. Some cows are given additional hormones to increase milk production.
Are you... serious? They have no problem with it BECAUSE they are baby animals! The hormones are IN THE MILK FOR THE BABIES. That's WHY babies drink milk, why mothers ONLY PRODUCE MILK FOR BABIES, why no other creature on earth drinks the milk of a mammal when they are not a baby. Like holy fuck, how do people think mammals work??
