Michael Phelps Celebrates Boomer's 1st Birthday With a Shark-Themed Bash

Boomer Phelps celebrated his first birthday on Friday. In honor of the big milestone, Michael and Nicole Phelps threw their little guy an aquatic-themed bash titled "Boomer's First Shark Attack." Aside from sharing numerous photos of the 1-year-old opening his presents, the Olympic swimmer also posted an adorable photo of the family of three with his shark cake.

It seems like just yesterday that Boomer stole our hearts at the Rio Olympics. Since then, he has been racking up even more precious moments on Instagram. Whether he's learning how to swim with his dad or just posing for the camera, we can't get enough of that sweet face.
