Found this interesting chart about how many times pumping is recommended here:
http://www.bodybeauty.co.za/breast.html

If the link doesn't work it says...

A session takes 10min or less and can be taken as follows:

Days after menstrual Cycle Result Times per week

1-7 Strengthening Period Twice

7-17 Breast Enhancing Period Every 2nd day or every day

17-24 Consolidation Period Three times

During menstrual Cycle Not Recommended


Not sure if this has been discussed at all before but thought I'd share.
