Pumping advice needed

My LO is 2 months old and so far I've only pumped a handful of times. My son still eats every hour and a half so it's hard to pump in between feedings bc then I'm basically pumping all day. Also, when he's done eating he wants to play. I really need to start pumping so he gets used to the bottle before I go back to work. Any advice on pumping? Or words or encouragement to get me motivated would be greatly appreciated 😊
