Boy, I could have USED some "milk duct tape" when I was nursing my two daughters. I'd be going down the supermarket isle in full winter clothes with baby in the cart, and if they started crying, my brain would send the green light message to my boobs and the milk would start dripping enthusiastically, regardless of the time and place or convenience. Milk duct tape would have been perfect. As it was, I had to use the old nursing mother's trick of "casually" crossing my arms and pressing them over the "spigots" until they calmed down again.
