Isn't it more to do with not eating/drinking stuff that comes from other animals but your own milk would be ok? Plus it's not processed and is completely natural... I'm thinking about it now!
How did I not see the damn link on this thread! Doh... What an entirely stupid couple. Vegan/vegatarians is generally a lifestyle choice, why can't children be left to make that choice for themselves.
Oh! Don't get me wrong. Obviously not feeding a baby of that any solids is plain wrong.
The story just got me thinking that maybe strict vegans would baulk at the idea of breastfeeding.
