I have reviewed your query and here is my advice. What your kid is having is not a diarrhea and is only a gastro-colic reflux. It is quite common for babies of this age group t pass small amount of diarrhea or loose stools soon after feeds. This need not be treated as diarrhea and especially antibiotics are not indicated. When the baby takes milk , the stomach expands - then when it is contracting it sets off a wave form which moves down the intestines and when that wave reaches the lower down rectum, a small quantity of the stool is evacuated out. This is the basis for gastro-colic reflex. Do not worry. 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.
