Girls, I talked about the child's allergy. What I'm looking for is another product. They prescribed me Zodak which I didn't buy and to keep a food diary. Well, we don't have an allergy to any specific product... I thought maybe we have problems with the gut after surgery. We've been taking it for a long time but maybe we haven't been drinking enough prebiotics...now we need to restore the microbiome... Is there safe treatment for the gut for a child? They recommended Bifidobacterium, I'm still studying it.
