I'm not sure it really counts as running WWB, and I'm not sure how long I'll keep it up (DD is determined I will, though). Know what you mean, MrsJC - I have a very old, and now completely the wrong size sports bra that I wore (new one on order from Bravissimo!), and I still felt I had to keep my hands near my norks for extra support. Nursing bras, though I found mine very comfortable, definitely don't give much support.
