Insulted by cows milk

Rocket 🇨🇦

My girl is not drinking cows milk and hates it so far. She acts like I’ve played a mean prank on her. She guzzles water and is breastfed. I’ve tried mixing breast milk with the cows milk, but no luck. How do I do this?

Edit: I’m not asking about whether I should be introducing cows milk or not, only how to do it. Baby is self weaning off the breast and we have decided we want to try cows milk in addition to cheese and yogurt.
