Aspiration

I have read the topics on aspiration on here and just have a few questions. My twins have had the modifed barium swallow done to deterime that they are asperating into their lungs. They were put on a thickening agent called simply thick honey. Since they have been on it they have done nothing but projectile vomit. I called their GI specialist first thing this morning, but have yet to hear back from. So, I thought I’d see if anyone else has experienced this before. My girls seem to be so miserable now, and they were starting to get better with their acid reflux before this all started.
