My kid wants to go vegan

I finally had the talk with my kiddo (8 yr old) about where her food comes from.

I am vegan (I’ve only been vegan for about a month) but she asked me why I went vegan and I told her it’s because I love animals and I don’t want to support that industry anymore. I was vegetarian for a couple months before I made the leap into full veganism. So we dove into the conversation (as lightly as I could) about the meat and dairy industry and what her bacon, hamburgers, chicken nuggets and cheese are made of. I told her in so many words they live a life of suffering and it’s really sad.

She was immediately distraught and expressed how much she loves animals and that she immediately wanted to go vegan. I of course let her know I support any decision she makes. I started making her all my really yummy vegan substitutes for her favorite meals and so far she’s loved every one of them and how it tastes the same to her!

Her dad on the other hand is one of those people who scoffs at veganism and upon her telling her dad about wanting to go vegan he basically scolded her out of it (we co-parent so I can’t really control that narrative when I’m not around). She told me after spending a few days at her dad’s that he wasn’t going to buy her vegan food and support that lifestyle.

Wondering if anyone else has dealt with this and what you did in your situation to maybe convince the other parent? It’s her body. And I don’t think he should be making choices about her diet just because he doesn’t care. Mind you, he’s not living off the government or has any difficulty paying for groceries. He simply just doesn’t want to support it because he thinks veganism is stupid.

I really love how kind and compassionate she is and I never pushed this lifestyle on her. She was curious all on her own. She wants to do it for herself and I think that speaks volumes of the kind of kid she is.

Any advice would be appreciated!
