Most of the diarrhea
in children is caused by viruses. You need not worry about it unless, child is very dehydrated. Check for fever
and urine output. When child is not able to pass urine, that indicates child is very dehydrated. You can start treatment of diarrhea in home it self. Feed the child with plenty of water, mixed with salt and sugar. ORS
sachets are also available in pharmacy. Mix that powder in potable water and feed. Make sure that child is drinking pure water, because most of diarrhea are water born, cleanliness is also utmost important.
