nvnvgirl, maybe your baby got sick from the oleanders...Oleanders are one of the most poisonous plants that exist. Here's a link...Scroll down to where it says Toxicity.

That seriously could be the reason your baby was having pancreatitis. The link states that it has been known to be deadly, but that reactions to this plant include: nausea, vomitting, abdominal pain, diarrhea that may or may not contain blood, etc.
I'm glad your baby is doing better though!!
