Thank you for posting your question. Greenish mucoid stools are an absolutely normal occurrence in an exclusively breast fed infant and so is increased stool frequency( upto 20 times a day may be considered normal).This is because of a phenomenon known as gastrocolic reflex which causes reflex defecation in response to feed. Here the contents of the intestine do not get time to change colour and are excreted in the same colour as they are found in the small intestine. Thus if your child is being exclusively breasted, these symptoms are to be taken as normal especially in the face if a happy and normally growing child. Thus antibiotics are not indicated. Also, since it is a normal occurance, probiotics like bioflor are also not indicated. If it is the stool report that is causing the confusion then repeating the report before starting antibiotics would be my suggestion. Having said so I would suggest you also keep a watch on your child s symptoms.Any change, decreased feeding, decreased urine output or activity, faltering in weight gain should be reported and dealt with immediately.
