MLP, using miralax never changed the color of S's poop. Although he has had green poop at other times when things were moving too quickly through his intestines. Sorry I'm not much help!
Could the combination of the Folic Acid and the faster transit time of the faeces through the bowel from the Miralax be causing the green stool?? Or perhaps the Folic Acid alone??
You mean green is not normal????? I'm kidding but not for Grace. Yes the green pooh means fast transit and the Miralax is helping with the speed.
I added 1 spoon full of Metamucil (psyllium husk) too two cups water in between meals and it will helped bulk up stool.
