When I was pumping for DS I would do power pumping sessions in the evening where I would pump 15 minutes on, 15 minutes off for an hour or two. They say that simulates the cluster feeding babies do when they are trying to increase your supply. Hope it helps!
I can try that. And actually you just sparked my memory. The lactation consultant did tell me to take an hour where I might be just watching tv and pump during every commercial during that one hour show. That's similar to what you're saying. I totally forgot. Thanks for jogging my memory. So much info...so little brain space! lol
