Hello everyone! I've been taking antibiotics for five days now, and I gave my son enterosgel. But since last evening, he's been having tummy troubles - it hurts, gurgles, makes noises, has diarrhea but still cries and fusses. We do massages and stool evacuation, but it doesn't seem to help much. Has anyone experienced this before? How else can we help?
