We became vegans about 3 years ago after the birth of our 3rd child, at age 37. i realized I had to live a lot longer! Our teens had a hard time adjusting, especially going to a public school where the norm was to eat meat, and lots of processed foods. Anyway, make a long story short, my 15 year old son is totally vegan, my 16 year old daughter is mostly vegan (cheese is the killing point for her) and my 2 babies, 3 years and 21 months, are 100% vegans! We have no problems with their health, they hardly ever get sick, they are full of energy, maybe too much, and they love their fruits and veggies. My 3 year old knows the difference between "our meat and cheese" and the dead animal meat and yucky cheese. My youngest has low iron, but we supplemet him and of course, we all do B12. Dont change your morals and values for anyone, ever! Your children will thank you for it in the long run!
