You don't make a big deal about it.
You offer a variety of healthy, tasty foods as soon as they are old enough to eat them, and wait as long as feasible to introduce junk, and once introduced, keep it to a minimum. (Whenever I read a post from a mom whose toddler 'won't eat anything but chicken nuggets and french fries' ... I wonder why the child was being offered those foods in the first place. )
You understand that there is no catagory of special 'kiddy foods' -- and your toddler can eat the same lamb chops, brocolli, lasagna, carrots, and so on that you make for yourself and your husband -- so there's no need to warm up a separate jars of 'Gerber Graduates' or make a box of macaroni and cheese.
You don't make a child eat everything on his plate -- or even eat a single bite of a food that he really doesn't like,(I'm sure there are foods YOU don't like...) but neither do you function as a short order cook. You offer a reasonable assortment of healthy foods at each meal, so there will be SOMETHING he likes; or you offer him a choice between 2-3 healthy choices. (Not "What do you want for lunch?" but "Would you rather have a grilled cheese sandwich or a cup of yogurt for lunch?"
You recognize that no child has ever starved himself, and that most common 'kiddy foods' are VERY new inventions. Long before there were chicken nuggets, hot dogs, peanut butter and Kraft dinner, children ate what they were served, and grew and thrived.
