My Aunt who lives in Perth is nearly vegetarian... she still eats salmon :S Idk why. She was raising her two kids vegetarian, but then the oldest one, when she was like 3 or 4 went over to the neighbour's BBQ and ate a sausage, and now they can eat meat. It was annoying, my whole family had been saying that it's not right raising kids vegetarian, saying that parents should give them meat then let them choose whether or not to be vegetarian when they get older. But either way, you're still deciding what they're eating, so why is it wrong to choose for them to be vegetarian until they're old enough to choose for themselves?
I've had this argument before with someone. You raise your children up the way you eat, if your a vegetarian/vegan, that's how they will be raised. If you're catholic, they will have a catholic upbringing etc.
In the end you're depriving your child of something, and every parent just brings up their children the way they believe is right, once they're old enough they're going to make their own decisions regardless.
I was brought up a meat eating catholic, now I am neither. I don't blame or hate my mother for bringing me up that way, because she believed she was doing the right thing by me.
