I just started back to work today, but will only be working half days for a total of 20 hours. This morning I nursed my baby at 8 before I left, and then pumped at 10:30 and got 10 ounces from that session. He took two, three ounce bottles while I was away, one at 10 and one at 12, and I got home at 12:45. However, I only pumped once at 10:30. Is this okay to do since I have such oversupply? Or do I need to continue to pump each time he eats while I'm away?
