So much this!
When I had a kid, I’d already been vegan 13 years, but the experience of nursing really reignited my passion about it. I couldn’t believe my omnivore friends were dealing with all the emotions and exhaustion of feeding their mammal babies from their bodies, and continuing to eat dairy. I had mastitis at one point, which until then, I had only heard of in terms of cows. The connection was so intense for me.
But, really, unless someone’s seeking out info about veganism, they often have never made the connection that cows are just another mammal that gets pregnant and then creates milk for their baby.
Yay for you! Yay for veganism! Yay for your friend!
