How much of what should my 6 month old be eating?

My daughter is 6 month old, and she is in the 97th percentile… She has been at the top of the growth charts since she was born… She is now eating 3, 8oz bottles, and 2 jars of 1st foods (fruits) and 1 jar of 1st foods (vegetables), and a 1/4th cup of oatmeal cereal a day… My ped told me to start her on 2nd foods when she turned 6 months old, and I am trying to figure out what combination of 2nd foods is good… I am a first time mom that calls the ped about everything, and I am big on all natural… My daughter was fed until the meds I was on stopped my milk supply, and she is on organic food now… My ped said that I can call if I am confused, but I am trying to figure this out.. LOL I use gerber foods, and I was looking at all of the 2nd foods that they have, and I am not sure if I should start her on the single ingredient foods, or start with the mixed meals… Plus I am confused if I am not giving Abigail enough cereal… I was looking online, and most ppl give their babies cereal 3 times a day… I just give my daughter cereal an hour before bed… SO any nice advice would be nice… So how much of what 2nd foods should my daughter be getting per day… Like how many times should I be offering her fruits or veg, or now meets???? My daughter is 19.6lbs, so she eats a lot.. Lol…. Thanks for the advice…
