They said she have a amoeba according to her stool test. Now her stool is color light yellow. Can u help me what is the best medicine i can give to my baby. thanks [/INST] Hello and welcome to ‘Ask A Doctor’ service.  I have reviewed your query and here is my advice. It is unlikely for a 3 month old baby to be developing amoebiasis. I feel that it could be gastrocolic reflux as it is going on for the past 3 months.  Gastrocolic reflux is quite common for babies of this age group, and to pass small amount of diarrhea or loose stools soon after feeds. This need not be treated as diarrhea and especially antibiotics are not indicated.Unless the kid's having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting. You need not worry. Hope I have answered your query. Let me know if I can assist you further.Regards, Dr. Sumanth MBBS., DCH., DNB (Paed). </s>
