SandraHi Nicole,
I can't believe that no one has responded. I would love to hear of a natural alternative but since our children really are supposed to be getting a replacement dose, I don't know if I would switch to a remedy that is not proven. What did your sister in law suggest? Have they been used to treat this condition in the past? Have you tried it? If you have I would be interested in knowing those results. Thanks and good luck.
Sandra
