Thanks for your reply. Has anyone seen anything to suggest that this diet can negatively affect their health? I have not found anything to reliably suggest that it is dangerous yet.
As long as you do your research and plan their diet, making sure they get everything they need (especially omega 3s, B vitamins etc for brain development) it's healthy. But I do stress *research* and mean it to include vegan doctors who specialise in raising vegan kids.
"hooked on sugar and love their sausage rolls and pies" ?? At two years old?

.....if you are wondering about the negative health effects of feeding kids a vegan diet, you should also be wondering about the negative health effects of feeding kids food like that. Also, it is not "too late" at 2 years old. They are not going to suffer painful withdrawals from meat products hehehe. If people can switch to a vegan diet in their old age, then how easy it would be for a child.
I was having a conversation with my boyfriend recently about this topic. I would absolutely only feed my hypothetical child vegan food, as that is what is best for their health. However, when it comes to the social aspects, I wouldn't tell them they can't eat their friend's party food and things like that. They could make up their own mind in those situations- that way you'd never be blamed for 'forcing them' to do anything or forcing them to be 'different to all the other kids'. I do resent the fact that my parents raised me on such unhealthy animal-foods (not that they knew any better). It affected my health and my brain tremendously throughout school.
