I had a real cute birth plan in which I requested no males in my room (for religiouse reasons, though you don't have to explain yourself). My husband handed copies of the birth plan out at the nurses station, along with a basket of chocolate (just to kinda smooth things, KWIM?). We also brought along our own door sign, that said 'no males please'.
With that said, I have to admit although we weren't visited by any male nurses, the attending OB was male. *sigh* What can you do? He was the only doctor on call, so I didn't have much choice. And honestly, by the time he showed up (which was about the same time the baby was CROWNING!), I could've cared less about his gender. GW himself could've walked into that room and I'd've said "slap on some gloves, my man - let's get this baby out!"
Have a great delivery!!!!!
