Michael Phelps' infant son, Boomer, might not be old enough to actually cheer for his daddy from the stands, but he did show his support with an adorable "Team Daddy" onesie during Phelps' swimming trials in Omaha, Nebraska on Tuesday.
Phelps' fiancée, model Nicole Johnson, brought her 1-month-old baby to watch his father compete, and posted a beaming snapshot the super cute swim fan. "#teamdaddy all day err day!!" Johnson, 30, captioned the precious pic.

In another photo shared to Boomer's own Instagram account on Tuesday, a photo of Johnson holding Boomer at the Omaha natatorium is captioned, "Mom and I are excited to go watch dad tonight!!"

Since welcoming Boomer on May 5, the proud parents haven't been able to stop sharing photos of their lovable bundle of joy. Here are some more sweet Boomer snapshots, just because.

Seriously, who would have thought that the baby of the world's greatest Olympian and a stunningly gorgeous model would turn out so cute?
Phelps, 31, is set to go to the 2016 Summer Olympics in Rio, which will be his fifth time competing in the games, and will try to add to his collection of Olympic Medals, because 22 just isn't enough.
