When my baby was born she was diagnosed with gerd in nicu. Was put on domstal. Now she is 8 weeks and her issue is she never puked after feed ( immediately or aftwr few hours ) She pukes or forcefully spits immediately after feed is started. She vomits once and vomit is sticky and has bubbles ( stomach acid) Sometimes this happens only once and afterward she takes whole feed and never purkes . Whatever puking is happening during feeding ( mostly when feeding is started then only forceful spit up happens ) She becomes restless . No vomit after feeding Why is this happening?? Pyrolic stenosis already ruled out.
