Questions for Moms (on baby food)

So we have started real baby food now. (Yes, it's the cutest thing ever.)
But, like with every new stage, I feel like I have a ton of questions.

Before we started baby food this was her routine:
Breakfast (right after waking up), 8am-ish:
-6-8oz of formula
-rice cereal (2oz of formula + rice cereal mix to right consistency)

Lunch (after morning nap), 11:30ish:
-6-8oz of formula
-rice cereal (2oz of formula + rice cereal mix to right consistency)

Snack (after afternoon nap), 3:30ish:
-6-8oz of formula

Dinner (after early evening cat nap or just later if no nap), 6:30ish:
-6-8oz of formula
-rice cereal (2oz of formula + rice cereal mix to right consistency)

Well, now she still has the same feeding times, but she will not take more than 4ozs of her bottle. I feel concerned by this because I feel like she should be having a bunch more milk. Also, I am still giving her the rice cereal too. Mainly because I wanted to have both to transition her. But now I'm thinking it's probably too much food. I am giving her 1/2 of a baby food container at each meal (not snack).

Here are my questions:
-Did your baby start taking less formula when they started baby food?
-How much baby food did you give at a feeding when they started eating baby food?

Feel free to pop in any more advice when it comes to feeding baby food.

Thankful for all y'alls advice!
