My friend has an 8 month old, whose babies appears to not only be allergic to banana, but seems to have a fit, and convulses a few hours after eating banana.

Sadly, she has been to a few doctors, but they won't acknowledge the severity of it, and she doesn't know what to do about it (of course, she knows feeding her banana is a definite no-no from now on!)

Has anyone ever heard of this before?
