I don't really know, so I'm not much help. I still EBF on demand (and not at all on a schedule) so I have no idea how many ounces she's getting. We do three meals and a few mum mum pieces during the day, but the amount she eats at each meal completely varies. I try to do 2 food cubes with some oatmeal sprinkled in. Some nights she wants more, but other times she only eats half of it. It completely depends on what it is.
We aren't quite 8 mos yet, but our list from the pedi has me giving 1 2nd stage jar plus oatmeal in the morning and another 2nd stage jar at night, plus we BF/bottle 6X a day. Sounds like you are doing fine!
My LO is not quite 8 months. We just started a 3rd meal this week. She went from 36 oz to 30 oz a day. We do 2 oz of food at each meal plus we mix in rice or oatmeal. She also has puffs for snacks.
Re: 8 monthers come in!
30-35 oz formula (down from almost 50 as a comparison..lol...big eater)
6-8 ozs of jarred food.
so...sounds like you are fine to me.
