Adventures in Potty Training

We started potty training "boot camp" this past weekend. Basically, both parents stay home Friday, Sat and Sunday and the toddler gets to be naked the whole time. Then, for the next 3 months your toddler is supposed to go without undies inside and outside the home.
Well, little man, you have been doing very well. The first day you partially peed in the floor about 4 times and pooped in the floor that night. Daddy and I took you outside for a while and for a trip around the neighborhood with no accidents. Not too bad.
Saturday you had no pee pee accidents, but did poop in the floor again on Sat night. We took you to the park on Sat and you used your travel potty in the back of the CRV...again, so proud!
Sunday, since you had been doing so well, we took you to the pool for the morning/afternoon. You used the travel potty a few times and again had no accidents. Man, this potty training is nothing.
Well...today (Monday), Mommy is so confident in her little boy...I take you shopping. We didn't shop for longer than 40 min in the first store b/c I thought you would need to try and use the potty. So, out to the CRV we go.

After sitting on the potty about 5 minutes, I'm ready to get you off b/c you always go right away when you have to go and I was hot (reminder, Mommy is almost 34 weeks along). But, you insist on staying on it. I let you stay a little longer, but you looked like you were just playing. So, on to the next store. Since you put up a fight about getting off the potty I thought I'd let you try again before going into the next store. I put you on the potty and still...nothing. Not even 5 minutes later...you're peeing and pooping in the store. So, with my blushing face...I very calmly, yet quickly exit the store...trying not to make eye contact with anyone. After a clean up and a reminder that pee and poop go in the potty, we head back in the store to clean up the pee. Luckily, your shorts contained the other. You've done so well with peeing that I wonder if you didn't pee in your potty b/c you were afraid you would poop too. I know you're not comfortable with pooping in the potty yet...I hope you are soon though!
So far, you've done really well and your Daddy and I are very pleased with how you are doing. However, I don't know if we'll be taking anymore shopping trips this week...maybe to the playground though. :)
