The proud father shared his love for his new son on Facebook
, already calling Koltyn his "mini me."
Locke penned a lengthy but heartwarming note to go with the photo collage. "Little man is just cruising through his first week of life," he wrote. "Hours in my arms or sleeping in my lap and I'm freaking myself out on how long I can just stare at him. So many unknowns in this experience and journey. I'm feeling beyond lucky that he is healthy and loves his Dad and his Mom so much. Can't wait for the adventures ahead."
