How long has DC had white poop? Has DC had any barium?(this is the only thing I can think of that would cause white poop, unless DC ate some white crayons or some old bones you used for bone broth)
I remember hearing about this a while ago, but don't remember the details. It may be some sort of liver blockage, but I recommend you take DC to a Ped to get them looked at. I don't want to worry you , but white poop in humans is not normal and could be something serious.
