We're having some success, too, though with another tack. Still doing Miralax, though I've reduced it to only half an adult dose per day, and have FINALLY (thank you insurance!) started high-dose probiotics. She's having regular-ish bms -- at least pretty much every day. So, like you, I'm happy. Before, even with Miralax, it wasn't every day. We had to go of it while she was in the hospital (four days), and, sure enough, no poop. But, we're back on and going . . . . .
