My newborn is 26day old. He recently kept vomiting after feeds. Sometimes reflux, sometimes Merlion! Normally only once Merlion. However tonight, he Merlion 5 times! Is it time to change milk powder? We breastfed, used stored Breastmilk, and formula. Doc asked us to mix due to jaundice. Any parents with similar case? Why does newborn always vomit after feeds?
