Not drinking enough?

Luca has always been up high on the growth chart percentiles and he is quite the little chunker. I feel like he isn’t getting enough formula in the day tho. I make 4 oz bottles and he doesn’t usually finish them. Today he’s had a total of 10 oz since he woke up this morning. But out of no where after I thought my milk had completely dried up, he’s been wanting to nurse. So on top of the 3 bottles for 10 oz he’s had two nursing sessions. One rite when he woke up this morning and one more just now after refusing the bottle. It’s so weird to me but he is starting to teeth now so I wonder if it began as a comfort thing and then he realized how shitty the formula tasted again 😅 anyone going through this? I will also add that he is peeing a lot throughout the day and pooping at least once a day so I’m not entirely concerned on the formula front.
