Hi Leila,
Did you ever find another vitamin? We're still using the Enfamil Poly-vi-sol with iron, though I'm looking for a better tasting alternative (that also doesn't stain so terribly...)
One of the reviews on Amazon mentioned something called Animal Parade liquid vitamins, but I haven't researched it yet..I might go to the health food store on Court and see what they have, too...
Thanks,
Tara
