At first, just a few spoonfuls. Eventually he'd eat about 2 oz in a serving. Once he was doing great with that and branching out beyond the starter foods, I started giving him a 4 oz bottle about 30 min before and 4 oz of puree. Now he eats 3 times a day and gets 4 oz of puree, some finger foods, and if he's still hungry 4 oz of formula. Often at dinner he just gets lots of finger foods and no puree.
We started at 5 months and did little tastes to get him used to it. Now at 6 months he is eating a whole pouch (4oz) mixed with cereal and a little Bmilk. Sometimes he is still hungry and wants a little milk chaser. Our pedi said to feed solids 1-2 meals a day at 6 months.
