With DD#1 when I was pushing and she was about to crown, I leaned back (I was squatting) after a particularly tough contraction. I could see my lady parts reflected in the doc's splash glasses and noticed he was about to cut an episiotomy. At that time I told him to move the scissors and that if he cut me I was gonna "kick him in the F$%@ing head".
With DD#2, I was coming out of transition with contractions triple peaking and lasting about 2 mins with very little break in between and suddenly I needed to push. I kind of knew that I'd been bearing down for a bit, but I was pretty roughed up after 48 hours on pit with no food...I leaned over and told OH to "push the button, I need to push". He patted me on the back and said "no you don't, you're just contracting really hard, honey" to which I grabbed him by the collar and hollered at the top of my lungs in his face "Push the f%&*#ing button, this baby's coming out!!!!"! The CNM was there before he even pushed the button and DD2 was born in less then 6 mins and 2 contractions. The docs didn't make it, the peds doc didn't make it and the room wasn't even ready for a newborn yet! I think the first words out of my mouth were,"I told you I had to push."
