Potty Training S.O.S.

Yeah, I posted about this not too long ago here. I'm still looking for anyone who might be able to help me out because I'm seriously frustrated. No, after 4 kids I do not have it all figured out. Bugs the crap out of me! LOL! So this morning we had another lovely poop incident with Lauren. Nothing catastrophically disgusting, but gross enough. I'd given her her undies to change into as I usually do. It wasn't until she'd pulled her diaper off saying, "Ewww!" that I realized she must have pooped in it and didn't tell me. Needless to say, I had to put her in the bathtub.

This girl is going to be 3 in about three months. She has been going pee on the potty since August or September of last year. What is the deal with the poop?!?! Joey was the SAME way. We had issues with Kyle, too, but I think he was still a little easier than both Joey and Lauren. Alec was the only one who did both at about the same time. Would putting her in underwear exclusively help? Because that is the only thing left I can think of to do. But if she is like her oldest brother, he couldn't have cared less. He pooped in his underwear and happily went about his business with it in his pants. So I don't know if that will do anything other than make it worse to clean up. Joey finally started pooping in the potty during a trip to Florida when he ran around naked most of the time. Our Florida visit is still 3 months away. Any other ideas?

Between the dog peeing all over everything (more incidents yesterday, including the discovery that he had peed in the infant carseat in the basement) and her pooping herself all the time, I'm about done! Kids and pets are gross.
