Am I feeding my 7 month old too much solid food?

I have a 7 month old that loooooves to eat. I started her on solids at 6 months. She even throws a fit if we eat in front of her and don't give her something for herself. She isn't fat or anything, I don't think. She probably weighs about 17 1/2 to 18 lbs. The doctor said her weight is normal, but I'm concerned that she isn't getting enough nutrition from her milk because she doesn't get as much as I have read that she needs. She eats five times a day and sleeps about 10 to 11 hours at night. Her feeding schedule is basically as follows: 1st feeding - 4 ounces prune juice mixed with a little water and apple juice (she has had awful battles with constipation and this is the only thing that worked after I took her off of rice cereal) and 4 ounces of formula; 2nd, 3rd and 4th feedings - 1/8 cup mashed vegetable mixed with 1 tbsp of ground chicken and 1/2 tsp of flaxseed, 1/16 cup of mashed fruit, and 3-4 ounces of formula; 5th feeding - 8 ounces of formula. She also likes to have one, maybe two, snacks in between meals, like a little bit of apple or maybe water with a little apple juice. I am very picky about what I feed her. I only give her organic fruits and vegetables that I make myself, and organic formula. She is a pretty happy baby, but does this sound like a normal feeding system for such a young baby? Thanks in advance for your advice! I would ask my mother-in-law, but she drives me CRAZY!!!!! LOL
