Potty Training Philip

Everything that worked for the first child, does not work for the second child. Philip has been the worst with getting interested in the potty! Wasn't until Kepler went to school that Philip said, I want to go on the potty, both upstairs and downstairs. After that I went and bought him a few presents and candy and lots of drinks and did the toilet training. He has the pee pee down packed. In fact he can pee on command. I kid you not, I'm laughing as I'm writing this. However, poop is a completely different matter. We had a few accidents, not too messy, but he didn't quite get to the potty for the poop. So, what does Philip do, not go poop at all for a day. I'm just not looking forward to tomorrow, afraid of when it does come....
