Eating too much??

Amanda

My son just turned a month and seriously lives on the boob. I only have a week and a half left before I go back to work so we started introducing the bottle. But he’s eating 4oz every 1 1/2 hours! Idk how I’m going to be able to make enough when I’m back at work. I have some milk saved, but not enough if he’s eating that much! Is that too much for him to be eating?? He starts screaming at an hour and a half and only feeding him calms him.
