Ftm question

I’m a ftm so this is all new for me. I’m wondering when it is normal to drop from 4 bottles to 3 bottles and if that’s what my baby is doing? She used to drink 4 8oz bottles at 6 months and since then it reduced to 4 7oz bottles but now here is the current schedule at almost 9 months.

Currently she wakes at 630, has a 7oz bottle, and then breakfast around 730, then sleeps from 930-11 and has a 4oz bottle (today it was only 3oz!), lunch around 1230, then sleeps from 2-330 and has a 6-7oz bottle, dinner around 6, then has her bedtime bottle at 7 and it’s usually 7-8oz.

All in all she drinks usually between 24-28oz and eats 3 meals a day. I just want to make sure she’s getting enough calories from her bottles. Is this normal? She has a 9 month checkup soon so I will definitely bring it up then.
