My child has trisomy 18. Overall, she s in very good health. She s 7 years old. She s currently taking colozol for intestinal inflammation, florastor, vit d and a multi vitamin every day. Within the past two weeks, I ve noticed that she had dark brown spots in her stool. I was told it could be c-diff or perhaps blood? Is this very dangerous and can it be taken care of easily or could this be a potential problem for her.
