How many ounces of solids does your baby eat?

My baby girl will be 8 months on the 2nd. She eats about 2 ounces of solids at each feeding and I feed her 3 times a day. I think if I feed her more she will take it, but if I stop she seems satisfied too. So in total she eats about 6-7 ounces of solids a day. She is small. Weighs 16 lbs. She is formula fed and drinks about 24 ounces a day. She hasn't started crawling yet, but it looks like she will be getting there soon. I know babies tend to eat more when they start becoming more active. Just wondering what's the normal range of solids for babies at this age.
