~{ Wife 'POOPING' during Labor?}~?

My wife is having a baby boy, & I need to know what to expect! So,I have heard of women pooping during labor (while they are pushing). This sounds highly embaring and I was wondering how many women actually do this or is this just like the very few who experience this. Also, does one p gas during labor(while they push)? I have no idea waht to expect and I jsut want to be prepared for any embaring or other than "normal" bodily actions during pregnancy , labor and post pregnancy. thank you Also, will this cause me to get sent out of the room at my wife's most crucial time?
