Does my baby have reflux or what? possible thyroglossal duct cyst...?

My three y.o. son had reflux for 1 year. All the symptoms sound like reflux except no wt loss. My son was fed and he would fuss a lot and shoot vomit. Eventually, he stopped gaining wt. The doc can do a simple test at the hospital to tell if its reflux. The baby swallows barium (thick white substance) and the tech takes xray pics as the baby swallows. With my son, it would go down but shoot back up. Try keep the head of crib up, don't lay her down after eating, and ask your doc about the barium swallow test. ANyhow, good luck, I know what your going through!
