Hi B.,
I have been a vegetarian mainly since I was 14 (I say "mainly" b/c I did go thru a meat-eating time when I was around 20'ish). But anyways, my husband is mostly veg. he does eat some chicken. But I do NOT cook meat or even buy meat. He eats it when he is at work or sometimes when we eat out.
We have a 14 month old daughter who we are raising to be veg. And until she is about 12ish she won't be allowed to eat meat even if she wants to try it before then. Just like I will not let her eat cake, ice-cream, soda at this point just b/c other people are letting their kids eat that type of food. At this age it is really hard to explain things. But we just say something like "We don't eat that kind of food. It is not healthy for us." And then distract her with her own food.
I think it can be difficult but definetely possible to raise vegetarian children. I know an older woman who raised her 3 daughters as vegetarians. And an older couple who raised their son as a vegetarian.
Anyways, email if you want to talk or meetup.
