Fatherhood seems to agree well with Michael Phelps.

The Olympic swimmer posted this picture with his family and the spotlight is on his newborn son Boomer Robert Phelps.

He captioned the sweet photo: "Nothing like being home with the family!!!"

Together with his fiancée Nicole Johnson, winner of the Miss California USA 2010 pageant, the trio seems really content in the family. As to whether Boomer would inherit his dad's love for the swimming is something we look forward to!
