Vegan ,semi vegetarian mothers

First time mom here looking for some helpful and useful info. I eat mainly organic foods vegan vegetarian foods here & there I’ll won’t but I have a 1yr old as well & I wanted to know is it safe to feed him the same foods dietary that I do? Looking for some tips because at the moment I feed him the same as I do but my grandmother is telling me not too.. what should be best because non organic foods aren’t that good that’s why I don’t eat it to much . But I do but majority of the time I don’t thanks
