Brief Summary  
Probiotics are living microorganisms, when ingested in sufficient large amount confer a health benefit on the host. There is evidence that selected strains of probiotics decrease the duration of acute diarrhea. 
There are many  probiotics that are available to be used in children but the effectiveness of this probiotic are still not proven
          Hence there is a need for a Randomised study to compare the effectiveness between three major probiotics such as Saccharomyces boulardii, Bacillus clausii and lactic acid bacillus
