Olympian Michael Phelps is known for his golden performances in the pool. Now his son Boomer is taking the plunge.
Phelps came home to Baltimore for the holidays and brought Boomer to the Meadowbrook Aquatic Center - where Phelps used to train.
The retired competitive swimmer went live on Facebook with a video of Boomer's swimming lesson with Miss Cathy - the woman who taught Phelps how to swim as a kid.
This was Boomer's third lesson with Miss Cathy. He'll be 7 months old next week on Monday, Dec. 5.
