Welcomr to the boards! My son has never eaten meat, and he's turning 2 in a couple of weeks. He's a very healthy little boy. He did get the flu last year when he was 10 months old, he was in the sucking on the shopping cart handle phase. This year he hasn't had more than a runny nose for a couple of days.
A good question for those who ask if your kids get sick alot from not eating meat...."How often do your kids get sick?" More than likely it won't be much more than how often your kids get sick. Then the person will see what a stupid question that is to ask. I was a meat eater when I was a kid, and I NEVER got sick. I don't think eating meat, or not eating meat makes a person more inclined to be sick.
At any rate, you'll find there are alot of veg*n families on these boards, who are always more than willing to give moral support when needed.
