Re: any nurses or doctors?
Undigested food in the stool is definitely a symptom of an unbalanced gut system. I would recommend checking out the book "gut and psychology syndrome" by Natasha Campbell-McBride. There is a lot of great information in that book about healing your child's gut and immune system naturally. The diet in it is, by default, gluten-free as it is also grain-free. The goal is to heal the child's issues so that they can go back to eating normally, and the younger you start, the quicker the process is!
