pumping in my office, what sign should I put on my door?

[Kunkle]

I work in the business office at a high school (share an office). There are 7 expectant mamas right now and a couple with LO's at home, so they just established a pumping room. I am still wondering if we need a sign for the door? "In use"? I think a simple Do Not Disturb would work in your case!

My sign says "Privacy Please". I work at an obgyn & everyone knows what I'm doing. There are no doors that lock, I just use one of the physician's office.. I'm going to put a door stopper in my pumping bag now!
