I can't believe we're coming up on 4 years of Kai as our son. Sharing our journey again, how can I not?! His life has transformed our family in so many ways. He's been through tremendous suffering, loss and health issues and yet he lives life with as much joy and bravery as anyone I know. He is one of my heroes. When we watch this, he tells me, "Mommy, soon we'll have a video like this for Ella too."
