I didn't want to cut down the amount of formula he was getting, to make sure he was getting all the right nutrients and such, so I did not mix anything into the formula. But since he was used to getting food from my hands, I finely diced some veggies and fed it from my fingers. This way he got to taste and knew it was food (since obviously my hands produce food, to him anyway!) and after a week or so I began to leave food, again finely diced, in a white shallow (and heavy to prevent tipping) dish for him to play with. Also millet, so he could learn how to eat seeds. As he tried more and more foods, then finely dicing wasn't that important and could introduce more seeds, etc.
