This thread has me laughing so hard I'm crying.
You can forget that it's a BABY that you are pushing out. I remember being surprised for a second after my boys were born. I'd been so wrapped up in pushing that I lost track of the purpose.
That you might not care to look at the strategically placed mirror between you legs or to reach down and feel the crowning head. I know this is supposed to encourage you to carry on, but I was way too busy to expend any extra energy feeling the head. I could care less what was coming out of me - I just wanted it OUT!
You might not even notice the sex at first. To me, the gender of my baby was totally not important in those first moments. I didn't even register their tiny penises for several minutes.
Do NOT eat bacon and eggs for breakfast if you think you may be going into early labor. I puked up nasty crumbly bacon bits contantly through my second labor - every ten minutes my head was in a bucket.
This has been mentioned I think, but you might still poop even if you've had an enema or diarrhea. I was sh**ting almost as often as I was puking with my second, but I still gave my Dr. a very nice present just before my DS crowned.
That you may not want your mother there and it's ok to kick her (or anyone else who annoys you) out of the room.
You do NOT need a crib or bassinet!
This one has been mentioned several times, but I think it's the most important. Breastfeeding does hurt at first.
Having excruciatingly sore nipples for a week or two is perfectly normal and does not necessarily signal any problems. NONE of the books tell you this. They all say that pain signals latch problems. I was so worried that I was doing something wrong. I always tell first time moms about this and let them know that while you may feel like screaming while the baby is latching on at first, it's normal and it will go away soon!
And one that I wish I DIDN'T know: That afterbirth pains get worse with each child. Yikes, I'm already nervous about dealing with them and I'm only 5 weeks into my 3rd pregnancy.
