my 21 days old daughter is 2 kg 300gms she poops after every feed and many times gives out milk and doesn't burp. what should i do so that she gains weight

A. the recurrent stretching / curving of the body again and again as well as uncomfort / making grunting sounds as well as hiccups as well as colic pain all are due to gas in the intestine and stomach. it is very important that after giving milk to the child you should keep the child in upright position and do burping for 15 to 20 minutes. do not keep the child back on the bed after 1 burping because one time burping widll not remove all the gas and if the gas is not removed properly it will lead to colic pain and more hiccups again and again. keep the chixld in upright position whether you hear the burping sound or not and also it is not important that you will hear the sound when the child removes the air from the oral cavity.
