Kieffer, who is currently pregnant with her third child, shares two children with husband Matt Kieffer—daughter Mia, and their unborn baby. In the statement, Lizzie explained that doctors later found a large mass on Lily’s brain, which had gone undetected due to the absence of symptoms. Further medical testing will be needed to determine more about the condition, a process that may take months.

“We are shattered,” Lizzie wrote. “Our hearts, our bodies, our souls ache for her as she was the purest of beings and brought light to every single space.” She also shared that despite Lily’s short life—spanning just 374 days—her presence left a profound and lasting impact on their family.

Addressing Lily directly in the message, Kieffer expressed her enduring love: “You’re our light in this darkness, and we know God is holding you in an extra special place.”

The post received an outpouring of support from followers and fellow influencers, including Madeline Custer, who offered prayers and urged the community to assist in any way possible. Amid unimaginable grief, the Kieffer family continues to be embraced by a supportive and compassionate community.
