My understanding is not entirely consistent with this. As far as we have
seen from the cel-pro experts, the current state of the art in genetics
research on Celiac is pretty much limited to HLA typing. If you new baby
shares the same HLA markers as your celiac child, the probability for the
baby to eventually manifest CD is somewhere in the 30-40% range (the
following is quoted from the file available at [log in to unmask] by
sending the command GET CEL-HLA ):

In the early days of our list, Kalle Reichelt cited some journal articles
showing that gluten does indeed carry over into mother's milk, although the
amounts are small. Don Kasarda told me that while he has never seen any
research on point, he would expect cows milk NOT to have any gluten due to
the very different "two-stomach" bovine digestive system.
My non-celiac wife feels there is a clear difference in our baby's behavior
when she consumed gluten and/or casein, so she stopped eating them, and plans
to keep them out of her diet until she stops nursing. Admittedly,
this is not a double-blind, placebo controlled experiment!
