Fi, Just a question, Did Jenna seem to be awake during this yet unresponsive or was she alert?? The only reason I ask this is because at around the same age my little brother started to have night terrorrs where he would seem like he was awake but was infact asleep and having these terrors. If that is what it was the only thing you can really do is sit ith her through out it. Otherwise goodluck on finding out what it is...

Oh yeah and on the spew, it was chunky But not nearly as bad as the one that followed.
