Baby led weaning

I’ve pretty much done everything “by the book”. Except I introduced puréed baby food to my son at 4 months and now at 6 he eats very well. He can eat a whole jar of stage 2. Now I see a lot of women giving their 6 month olds regular food. If they’re eating at the dinner table they will give their baby stuff. My sons teeth haven’t erupted yet and I am wondering what he can and can’t have or what you ladies do? He is always very interested in what I’m eating. He will try anything if I let him. He’s loved every flavor of baby food so far.
