Day 3, hour 2 - Getting it?

We haven't had any success this morning, but between timers, Henry told me that he wanted the iPad ("Bye-bah," he yelled at me).  I told him that he could have it when he goes pee pee in the potty or when the timer goes off.  He walked over to the potty and sat there while he was playing with his blocks.  After about 5 minutes, he called over to me and I asked if he'd peed.  He shook his head yes, held his penis, and hopped off the potty to show me.  There was a drop of liquid in the potty which may have actually been pee, but just as easily could have been condensation from the water cup he's been carrying around.  Regardless of what it was, he seemed to put together that something was supposed to come from his penis and be in the potty in order for him to be rewarded.  So.  Huge progress, right?  Maybe it IS working!
