I've been pescatarian/vegetarian for years now, mainly for health reasons, but the rest of my family all eat meat. DD1 is 12 and she wants to become vegetarian too. I feel she should be old enough to make her own decision but can't help feeling worried about her not getting enough protein/ food in general. She's healthy, but very skinny and I'm worried about a possible eating disorder in the future (one of her friends is anorexic and there have been a couple of cases of bulimia in her year). Still I feel I can't really say no as I have been vegetarian for so long and am healthy. AIBU?
