Before she was born, Jim Sitton had nicknamed her “our rainbow baby” and wrote a beautiful poem to her, saying she was the rainbow God sent them after a terrible storm. She brings colors into their black and blue lives.

The Sittons chose the name Natalia because it was Makayla’s favorite name and because it means “Christ’s birthday” or “born on Christmas” and that was Makayla’s favorite time of year. Her middle name is “Grace” to celebrate God’s grace on them.
