Yeah my D6 had that bottom closing problem too. It did clear it up, you're right.
H said the same thing about A&D last night so I may pack em up and go buy some. She's had diarrhea for 2 solid weeks now (ever since being weaned from breast milk to cows milk) around the clock and she is paying the price, poor wee lassie! Today seems a little bit better than yesterday, though, so I will call it an improvement. She still shrieks like a banshee every time she goes to the bathroom and has this pitiful bowlegged walk (can you even imagine a baby walking bowlegged cause it hurts? It is heartbreaking!) but she'll pull through. She won't drink soy milk and formula's so blasted expensive and smelly, I was hoping to avoid it. Ah well, that's life right!
