Diarrhea may or may not be associated with vomiting. As with vomiting, avoiding dehydration is key. Dehydration is when a child's fluids become so low that her body cannot function effeciently. Signs of dehydration include crying without tears, dry mouth and tongue, decreased voiding (or wet diapers, sometimes difficult to tell with diarrhea) and/or listlessness.
Mild diarrhea usually resolves by itself. Moderate diarrhea often requires a dietary change. Discontinue solid foods temporarily and milk products. Start your child on an electrolyte solution to replace fluids and salts lost in diarrhea. Do not try to prepare these solutions at home. Use only commercially available solutions. If your child is not vomiting, give as much fluid as she will take. (If she is vomiting, too much fluid may induce vomiting.)
When reintroducing solids, begin with bland foods, toast, crackers, rice, bananas, applesauce, plain yogurt, etc. Start Florastor Kids (probiotics) one packet BID mixed into apple sauce or yogurt. Keep using Florastor for 3 days after diarrhea has resolved.
Contact your pediatrician if your child is having blood or mucous in her stools, if her diarrhea persists despite your best efforts, if she develops a high fever (102 or above) or if you think she might be dehydrated
