My 3-year old has been vomiting for a couple of months now, starting with once daily, and now up to 30 times daily. He can't ingest anything (it's more like spitting up), and how is forcing himself to do it by sticking his fingers down this throat, or hitting his throat. In the middle of the night, he has severe post-nasal drip and wakes up throwing up. We've seen all kinds of doctors, with little help. Now, he's not ingesting anything. I've been reading up of GERD, and was wondering if this could be an answer. Thank you.
