“Philly raised little man will be! 💯👶🏼 #BabyHarper,” Harper captioned his photo set, which also included another snap featuring the front of the jacket and an ultrasound photo.

Harper and Kayla, 26, tied the knot back in December of 2016. “A year ago today I married my high school sweetheart in the pouring rain ✨,” the athlete captioned a snapshot of the couple laughing in their wedding-day clothes, which were soaking wet, on Dec. 16, 2017.

Kayla also posted a throwback picture from the day, writing, “I don’t think I’ll ever get sick of reminiscing about this magical day with you for the rest of my life. Happy Anniversary my love! 💍🤵🏼I love you #thesequel.”

In July, the couple enjoyed a “babymoon” vacation in Chattanooga, Tennessee, where they took time to relax on a boat before becoming parents for the first time.

And Kayla was honored at not one but two baby showers, including one August bash that took place in Nevada, with the theme, “Twinkle, Twinkle, Little Star.”
