When this started happening with both kids I switched to Pampers and Luvs (both made by the same people). I had much better luck and way less poop and pee leaks. Also, go buy some of those plastic diaper covers. They even make plastic covered training underpants that will soak up stuff if it makes it out of the diaper. These all help a ton!!! I could only find them at Kmart. Good luck!!!
