as priya said burp in between feed... and dnt burp immediately after feeding if baby is vomiting always during burping. hold in upright position for some time and then burp your baby.

Pls ensure that in between feeding the baby you burp the baby. <font color ="#3b5998"><b><a href="http://app.babychakra.com/article/1074">How should you Burp your Baby?</a></b></font> is a good read
