Hello Doctor, My son, age 5, has been complaining of stomach ache since morning. He passed loose motion thrice since morning. Twice in the last 30 mins. Since we were travelling by train since yesterday, we could not medicate him. We have now given him half sachet of Econorm [Saccharomyces Boulardii (Lyophilized)]. Since its quite late in the night and tomorrow is Sunday, request your guidance on how to handle this situation. Regards Mathew
