It is quite common for babies of this age group to pass a 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 kid takes food, the stomach expands - then when it is contracting it sets off a waveform 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 gastronomic reflex. Do not worry. Unless the kids having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. The other possibility when it related is passing motion immediately after food is that it could have been worm infestation. Hope I have answered your query. Let me know if I can assist you further.  </s>
