>Does anyone have a source or a recipie for GF communion wafers?  Our
>son's First Communion is coming up on May 7th.

Here's something from the Canadian Celiac Assoc.  Handbook 3rd Ed.
concerning a child's first Eucharist.

" Canon Law 925:

Holy Communion is to be given under the form of bread alone or under both
kinds in accord with the norm of the liturgical laws or even under the
form of wine alone in case of necessity.

A case of need for giving wine alone is demonstrated ''whenever a person
is physically or psychologically unable - whether permanently or
temporarily - to consume the Eucaharistic bread''.  Those with celiac
disease qualify under this Law.

For those whose church would accept an alternative, the following is a
tested recipe for a gluten-free Host that may be brought in a sealed
container to the church, hand to a member of the clergy, and blessed
along with the gluten containing Hosts.

Gluten-Free Communion Wafers

2tbsps potato starch flour      1 tsp baking soda
1 cup minus 2 tbsps cornstarch  1 tsp salt
2 cups brown or white rice flour
2tbsps xanthan gum              3 tbsps plus 1 1/2 tsp sugar
1/2 cup butter or margarine     1 cup buttermilk

Sift the dry ingredients together.  Cut in butter, add buttermilk, and
mix with fingers until dough is workable.  Roll with rolling pin on rice
flour coated surface as thin as possible.  Cut into small circles.  Place
on cookie sheet.  Bake at 350 F for 6 minutes.  (NOTE:  They do not
brown) "

I hope this can be of some help
