Whole Milk Schedule?

Hi ladies! Hope everyone is keeping safe and healthy!

My little guy is fully on whole milk now. We have yet to transition to sippy cups he protest pretty badly. He takes three bottles

8am- 7oz followed by breakfast

12:30am- 7oz followed by lunch

7:00pm- 7 oz bedtime

I’ve noticed he doesn’t really finish lunch after his second bottle of the day. His pediatrician said we can start to drop the afternoon bottle when I start to notice.

Is around 14oz of milk a day sufficient enough then? He also doesn’t really drink too much water I think cause he is so full from all the milk. It’s so hard to tell! Just looking for some insights.
