Omg congratulations love I just seen this💖

It’s normal to overproduce in the beginning and he won’t be able to consume both sides. You can buy these little things called milkies that can catch the leaking milk on the other side. I did it with my son and I was able to store up several ounces. With my daughter I just let it leak into a rag. Between feedings you can hand express if you get too full but don’t pump because you will fill right back up. After a few weeks you will regulate.
