Feeding scedule

So excuse me if this is stupid, but I cannot seem to get LO on a feeding schedule. He has reflux so idk if that has anything to do with it. He loves snacking. As you all know we are going through the regression and I'm wondering if I can get a schedule down because then I will know when he is hungry and not. He eats anywhere from 26-34 oz a day depending. How did you guys get your LO on a feeding schedule? We've started gentle sleep training, may as well get all of our ducks in a row now!
