Breastfeeding after exclusive pumping 3 week old

Hi ladies, I need some help and advice. My baby came a little at 37 weeks and was high 5 lbs low 6 lbs. He latched really well the first few days until my milk fully came in and started having issues, I’m also large chested so I felt to big for him at the time, so I started exclusively pumping and bottle feeding until today. I decided to latch him today and start trying to breastfeed again now that he’s bigger. He’s latching pretty well but I don’t how much he’s getting. Or if he’s getting enough. He popped on and off in the beginning and then once latched really good he stayed on for 10 minutes. And came off burped and I offered the other side but he fell asleep. A 10 minute pump for me is 2-3 ounces on one side so I feel like he got enough but what should I be looking out for or should I be waking him to make him eat on the other side too? Has anyone successfully transitioned to breastfeeding after pumping for a few weeks? Should I keep pumping after he eats? I have had a bit of an oversupply so I am hoping to regulate it with him nursing but still pump for dad to give him a bottle a day.
