Earlier quoted context omitted.
Unless carefully managed, a vegan diet has a chance of lacking some critical nutrients for the development of young children. I think a vitamin B12 deficiency is common.
My ex had the same issue while on a vegan diet - and she was an adult. Random dizzy spells and faintness to the point of almost passing out. It boggles my mind anyone would ascribe to a diet that literally requires vitamin supplements through artificial means in order to be complete. And those are just the obvious deficiencies.
I used to think that, but at some point I thought: what's the big deal? If you're still eating healthy, still eating tasty food, and you just also consume a pill or two every day, is that really so bad, or does it just feel "wrong"?
