Contemplating a 6 month old's diet: Bottle Vs. Solids

Since we've started Monster on solids, I've tried to develop mealtimes for him so that he learns a routine when it comes to eating. We feed him a fruit and cereal breakfast, then veggies for lunch and supper with all the appropriate bottles in between. He drinks approximately 40 ounces of infant formula a day, with said meals between.

Our current day looks something like this:

6-8am: Monster wakes up - 8 ounce bottle

9-10:30am: 2nd breakfast - Fruit and Rice Cereal
10-11:30am: 2nd breakfast continued - 5 ounce bottle

12:30-1pm: Lunch - Veggies
2-4pm: Afternoon pre-nap snack - 8 ounce bottle

5-6:30pm: Supper - 6-8 ounce bottle, and veggies
7:30-9pm: Bedtime Bottle - 8 ounces

Sometimes we end up skipping the veggies at lunch, and the ounces per bottle vary (give or take about two ounces) depending on his hunger that day, or his growth.

What I'm contemplating, is how much things are going to change once he reaches the six month age, and his food varieties grow immensely. When you start introducing foods and meal times it's supposed to begin replacing breast milk or infant formula (not completely) but at what time does the solids meal out rank the meal from the boob or bottle?
