1st do burp well after feeding , keep head 30 degree up from chest....you can give domstal for couple of days...digipen is for digestion..

Domstal is ok . Don’t know what Digipen is. Please send it’s scientific name

Domstal is for vomiting and digipen drops is digestive enzymes. If child is on mother’s milk and spit it out small quantity its normal no need to give any medicine. Just do burping more. But if child spits out more and child is losing weight or urine is low then you can give medicine for vomiting and more frequently breastfeed.

Little bit vomiting immediately after feed is called regurgitation .one to two  small spitting in a day  is perfectly fine . Please don't rush with medicine . First try good burp post feed followed by positioning the baby in right or left lateral position for next 20-30 min before putting in supine(face up) position .
