Re: foremilk/hindmilk imbalance and pumping
You can freeze any extra milk you pump to use later if you need it. I had f/h milk imbalance, though never had an oversupply problem. I just tried to look at the milk I pumped to see if it looked 'creamy' enough. You can tell the foremil when you pump because it looks blueish and sort of clear. Also, once it starts to separate you can see how thick the cream layer is on top.
If you don't think there is enough hindmilk, you can try giving the breast a brief break (a few minutes-I pump the opposite side during this time) then pumping again to get another let down. I have to pump really rapidly for a minute or two to get another letdown, but it is usually the one with a lot of hindmilk and makes the milk look really thick and white.
As for pumping on only one side, I'm not sure. It seems like this would help with the oversupply issues, but I have no experience with that so hopefully someone else can chime in on that.
