"It is with a heavy heart that we share with all of you that Talia has earned her wings at 11:22am. Please lift her beautiful soul, her beautiful light to heaven and please send your love and prayers to her family during this most difficult time," a Tuesday post on her Facebook page said. "God speed little one, may you be free from pain and suffering, may your soul feel the light and love that you brought to so many of us on this Earth during the short time you were her[e] with us. We will miss you more than you will ever know baby girl."
