But from what I read, and assuming they get B12 through breast milk (and assuming mother is B12 replete, if she is vegan and not taking B12 supplements she may not be) then there may be ? 3 years maybe more supply in the liver.
So will they be able to reach 18 in order to make their own decision??
Is imposing veganism on children without supplementing their B12 intake a form of neglect?
(Sorry @Oldvater, you probably did not post this thread expecting an 'neglect' angle)??
