If You See A Purple Butterfly Sticker Near A Newborn, Here’s What It Means
Millie Smith and Lewis Cann found out they were having twin girls, but only one of them would survive.

Smith gave birth to identical twins Callie and Skye on April 30, following a high-risk pregnancy that lasted 30 weeks. Skye only lived for three hours.

Without her sister, Callie spent the night in the NICU incubator under the watchful eyes of her adoring and distraught parents.

An exhausted mother of healthy newborn twins told Smith, in all candor, that she was “so lucky” not to have two infants.

The statements devastated the new mother, and she was at a loss for words. Then she saw the purple butterfly and knew that Skye’s legacy was to comfort other bereaved parents.
