What does your pediatrician have to say about this? As long as he or she is fine with your baby's health and development, then I wouldn't worry at all! The only thing that I see that is somewhat different than what I am used to is that the baby eats 7 times a day, but I'm going to guess the constant snacking/smaller meals helps with the reflux. My 8 month old baby takes 25 ounces (1 ounce less than yours), but over 4 meals and an occasional snack.
The only question I might ask your pediatrician would be "could the all-day grazing be contributing to her weight?". Again, if the pediatrician is satisfied with the growth then no need to worry.
