Important Note: I didn't intend for this to be a weekly series, but dammit, I've got a lot of messages. So for those that are bored by the MTFP series, I've got a small bag of TOO BAD for you.
There are a zillion books out there that describe pregnancy and birth experience, but most I've seen are geared towards the woman. Sure, 100% of births involve women, but sometimes, the baby's daddy is there also. With that in mind, I've pulled together a list of things to DO or DON'T do for expecting fathers during the birth experience.
Other Important Note: That last sentence may not be gramatically correct. It's an awkward apostrophe situation saying "do's and don'ts," and "dos and don'ts" just doesnt' look right. I struggled over that for a while. Most of the day, actually.
DON'T get a horrified look on your face when the doctor has to go in and break your baby's momma's "bag of waters" (if it hasn't happened naturally already). It's just amniotic fluid tainted with baby pee, it's really no big deal. You swam in it for 9 months yourself. Oh, and there's a lot of it, and it comes out with force. So be prepared for that. Just kinda go with the flow and act like it's fine. Using the word "fountain" is frowned upon.

DO whatever she says. It doesn't matter, just do it.

DON'T bring it up when she tells you to do the opposite thing ten minutes later. Let it go.

DON'T complain that your back and leg are getting sore from standing next to the bed for so long. Likewise, keep any complaints about the amount of sleep you got last night to yourself.

DO know where the button is to call the nurse. And the remote for the TV.

DON'T tell her to "hang on a sec" while watching the TV. Even if it's your favorite episode of Saved by the Bell.

DO remember to have the camera ready for once the baby is born, you'll both appreciate it later.

DON'T get the camera out too soon.

Finally, DON'T be a wuss and sit in the waiting room and miss an amazing experience. Or be in the room and faint. Don't do that either.

With these things in mind, you guys out there should have a very pleasant birth experience. Ladies, even with more prepared guys, it's still probably going to suck for you (but in a good way). No advice I give is going to change that.
