The Poop Scoop

Here's the poop scoop in our house:
1) Today David started talking potty talk. He screamed sorry so many times while I pulled out the jug of vinegar. He sounded like he was going to hate it. I put about a tablespoon in his mouth. He swallowed it, looked at me very matter-of-fact and said, "I didn't cry." And he calmly walked away. The potty talk stopped, but I'm not sure the threat of vinegar in the mouth is going to be very effective anymore.
2) David is still not willing to go #2 in the potty. He's been successfully going pee-pee for almost 2 months now. Yesterday, like every other day, he brought me a pull-up and asked for me to put it on him to go poop. This time I refused. I told him, like always, poop goes in the potty. And that he'd have to put the pull-up on himself if he wanted to poop in it. He struggled for about 5 minutes, fussing the whole time. He so wanted my attention with the entire process. I told him that when the pull-ups are all gone he'll have to put poop in the potty and then I left him alone. Today we had the same scene. I think we have 3 pull-ups left in the house.
3) Can I hear an alleluia chorus --- I refuse to wipe my 5 yr old's bottom anymore! I know this was more my issue than hers. She's just always asked for help because she doesn't want her panties dirty. I've just always obliged because she's my baby. (well...err...she's not really a baby anymore now....is she?!)
