Both my kids were on miralax for the last 1 & 3 years. Since switching to begin health probiotics, my 5 year old has had regular poops with absolutely no miralax on board, and my 2 year old has been somewhat regular but does require a tiny dose of mirlax in her morning juice every few days to keep her poops a healthier texture. She has had some GI problems since early on though so for us this is a win.
