G.W.
I always would do one side at a time to empty it. And I would just switch each time. I also fed on demand. I would keep up with which side was next by wearing a ring on my thumb and would put it on the side that was to be the next feeding during the current feeding. I also had some huge let downs where milk would spray out. Sometimes my daughter had a milk face bath. (No worry - I am sure somewhere that is considered a luxurious spa treatment) So try sticking to one side at a time, but don't do just that side for 3 hours. Let him nurse as long as he likes on one side. Then do the other side when he is ready. Just go with the flow and relax. Good luck!
