### output:

Hi... Thank you for consulting in Chat Doctor. Passing stools soon after feeds is gastronomic reflex. Do not worry. It is physiological. What your kid is having is not a diarrhea and is only a gastronomic 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 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. Even if the kid is vomiting after feeds if his activity and development is age appropriate you need not worry. But if his weight is less than 5th gentile then it might be gastroesophageal reflex and needs evaluation. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
