I have so much to say to this. Ultimately, we disagree vehemently.
Infact, I wrote about this very topic. It’s more complex than veganism being a simple diet.
And children can get all the nutrients they need being vegan. I’ve worked in child protection, believe me, there are really sinister things going on in the world beyond feeding your child a carefully crafted and healthy vegan diet.
Note like all manners of food consumption just being vegan is not automatically healthy, just like all diets, so being informed and aware of nutrients required is essential.
