my boss is on maternity leave but came in for a couple of hours the other day, she told me I can use her office to pump until she returns. She does not have a lock on her office door (I have a cube, we do have a mother's room but this is more convenient). So I made up a sign for the door - it has a "Do Not Enter" followed by the driving do-not-enter sign, a picture of a Mom holding a baby and a picture of a cow (all pictures curtesy Word). LOL
Re: pumping Mom humor
Too funny! I used to put a sign on my classroom door that just said, "Do Not Disturb." I'm lucky that it has a lock, but I sent an email to everybody that has a master key, letting them know they really didn't want to come in unless they wanted a big surprise...
Now that I've stopped pumping I still have my sign - I wish I could put it out occasionally!
