Increase supply question

Hi! I’m new(ish) to EPing. I did it with my first but it was a learn as I go experience so this time it is much more successful. Right now I am pumping on average 3 oz every 2.5 hrs and she is almost 1 week and some change old. I’m curious what happens when her appetite grows and she’s going to need 4 ounces at a feeding. Do I need to up my supply? Will it naturally occur? Trying to get ahead of what to expect so I don’t run into the same problems as last time. Thanks!
