When to harrass worker (nicely of course)

Hubby and I are in the same boat! We have been waiting for a month as well for the supervisors signature. What also sucks for us is that it's not over at that point. It still has to go to a private company our agency pays to review their paperwork and make sure everything is in order. Once they make any needed edits, it goes to the state and then we have to wait for them. Ahhhhhhh! I hate the wait. I will keep my fingers crossed for a quick reply for all of us.
