Do I have the hungriest baby ever? Or should I be feeding him more solids?

At 7 months, out of one of the small jars, my kid will eat about half for breakfast and still seem hungry. He still gets all his milk feedings, so I'm not sure how much of the solids I should be allowing?

At 7 months, what is (or was) your baby eating for solids?

-hungriest baby ever.
