if you haven't figure this out yet..
it would work to get stuff from the health food store till you get something.. there is a product called Caricol and it is a papaya puree and is a great source of natural enzymes safe for your toddler, its not as affective as prescip. but better than nothing i would use a tube per feeding if possible. it is $20 for a box of 30. I actually use this to administer B's enzymes as a booster, he always sits at the high end and I can keep him in his prescribed range with this, otherwise I have to give him over his prescribed amount..
