The 41-year-old actress told E! News: "With a little boy, you have somebody who is going to love his mama. There's nothing like it."
The brunette beauty says her entire family are sports fanatics and love hosting American football parties for their friends.
She said: "(Ben) watches and I manage the chaos behind him so that he can watch. When I talk about managing chaos I'm talking about managing three little chaotic people, plus whatever friends bring their chaos over and we try to let the guys watch as much as we can."
She added: "My little dude does love a football. He can already sit and watch an entire game. He really gets it."
Asked about her daughters, Jennifer said: "They definitely care about being girly but they're definitely athletes. They're out there, they're ready to try out for sports, play hard and practice."
