(Newser) – Strands from baby's first haircut. The first tooth. Tiny footprints sunk into clay. Some parents even tuck away the dried stump of the umbilical cord or the stick pregnancy test as a touching memento marking the milestones of their kids. The latest? Breast milk jewelry, on sale at the handmade marketplace Etsy. Few issues polarize mothers more than breast-feeding, and all things related to breast-feeding, so wearing processed breast milk around the neck or in a bracelet has ignited some passions.

"This is the most hilariously absurd trend in mommy jewelry that I have ever heard about in my life," says one breast-feeding mom. "I think it is just flat-out weird, to be honest." The breast milk is covered with a glaze or clear resin after it is plasticized or dehydrated, forming a clay-like substance that hardens over time when 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 one product description. "This can be passed down for generations and what a fantastic gift to give to your child, the root of their survival." (Or if you'd rather ingest your own breast milk than wear it, consider breast milk cheese or breast milk ice cream.)
