Our child is just fifteen months old and has been doing well until recently. However, for some unknown reason, they’ve started experiencing diarrhea, which isn’t severe but is quite concerning. What should we do? This is usually caused by underdeveloped gastrointestinal function or improper diet, leading to dysentery. It is suggested to administer some digestive medications for treatment, but this must be done under a doctor’s guidance. Never give children medication arbitrarily; always use drugs suitable for infants. It is recommended to visit the hospital’s gastrointestinal department to check for any diseases related to the gastrointestinal system and see if the condition is caused by bacterial enteritis, and then exclude this possibility before proceeding with treatment.
