Want to have a unique memento of your child's infancy? There are crafters on Etsy who sell keepsakes made with dried breast milk. The Detroit Free Press reports:
A couple purveyors, both moms, said in interviews that they hit on the idea as they sought out unusual keepsakes of their special bonds with their babies during nursing.
The two would not reveal their recipes for processing the milk, which is covered with a glaze or clear resin after it is plasticized or dehydrated, forming a clay-like substance that hardens over time when at least one method is used. [...]
“What a wonderful way to preserve the ‘liquid gold’ that we are only able to make for a certain period of time,” reads the product description for the latter. “This can be passed down for generations and what a fantastic gift to give to your child, the root of their survival.”
