Hi A.,
Michelle is correct, breastmilk or formula is the main source of food at this moment 24-32oz per day. At this stage, he should be eating solids about twice per day. Baby food is used as a supplement to help fine tune their muscles in their jaw/face to help them prepare for real food when they are ready 12-14m. www.wholesomebabyfood.com is a great resource on feeding schedule.
Enjoy it, babies are intuitive eaters, they really do know exactly what their little bodies need, let him guide you. Unlike adults, we tend to eat when we are bored, depressed, happy, etc, we are not intuitive eaters...
Have fun,
