I put this in the announcement section of my site.
"My products are not intended for children under the age of 13. Note that I have not tested my items for lead per the CPSIA due to they are not intended for use by children and will not fit them."
Also, I have printed out labels that I apply to the bag each item is in stating that it is not intended for children.
I am also working on something for the California lead law. (Currently researching it.)
