Hi...Thank you for consulting in Health Care magic.
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.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
