I went out today and drank 1 mojito and 1 champagne. Must I pump and dump?

As a guide, it will take approximately two to three hours for one serving of wine to pass through the body. Therefore, you may need to wait for quite some time for the alcohol to pass through your system before nursing. Suring the wait, it is probably best that you pump and dump (or use the milk for some other functions) just to be on the safe side. :) For more information: http://www.llli.org/faq/alcohol.html
