WATCH: Ryan Lochte Prepares His Baby Son Caiden Zane for the 2036 Olympics Back in June, Lochte and fiancée Kayla Rae Reid shared the first photos of their newborn on Instagram, just six days after Reid’s 26-hour induced labor. Also on Thursday, the proud mother of one shared a loving dedication to the two loves in her life. “I am very lucky to have these two in my life. I have been blessed with a man who has a BIGGER HEART than anyone I know, goes above and BEYOND to make people feel welcomed, comforted, and loved,” Reid captioned a photo of Lochte holding up their son. “He cares about compassion, love, family, friends, making people smile, New York pizza, generosity, etc. Ryan still shocks me to this day of how much he puts everyone before himself. He falls down and gets right back up, which is so important and admirable,” the model continued.

These two boys mean the absolute world to me and I will do anything for them. I will forever appreciate my family.” Aside from becoming a dad in June and then marrying Reid in the fall, Lochte has been house hunting in Los Angeles — where he plans to pursue acting while training for the 2020 Tokyo Olympics. “I think everyone deserves a clean start and that’s what I love about this,” Lochte previously told PEOPLE.
