I breast fed my kid till 12 months.

yesterday, I boiled some soup for friend to boost her milk -- she took most of the soup, but left some, so I had it -- I do not like to waste food, anyway all food items, nothing harmful even to normal people -- but last night, I sense something a little strange on the breast, so I expressed with hand, some milk eject out!!!

anybody had such experience? can I resume the milk after wean for 6 months, given this happen?
