Big Boy in Training

We decided to bite the bullet and start potty training Jacob. This is the exact same age, down to the week, that Ethan learned to use the potty. Ethan was a total piece of cake so I'm expecting a bit more of a challenge with Jacob. Can't have two easy goes at potty training, can we? With Ethan, we were on vacation at the beach and he just ran around the house naked for a week. That seemed to work like a charm. Jacob refuses to be naked. He's got to have the big boy undies and shorts on. Not quite as uncomfortable as just peeing down your leg.
