"A year ago today, I was given the best gift I could ever have," Ron captioned the Instagram album above featuring photos from the toddler's first birthday bash. "I’ve been blessed to have been through more experiences than I could ever dreamed of. I’ve been blessed to have so many different gifts & blessing in my life. You think you have lived life when you have been through the things I’ve got to experience & go through. All of those things don’t even compare to the feeling I get when I laid eyes on her. She makes everything have a purpose & gives me [an] indescribable feeling. Daddy Loves You! Happy 1st Birthday Princess @ariana_sky_magro"
