Gotta start 'em young ... and Patrick and Brittany Mahomes are doing just that -- 'cause their 2-year-old daughter, Sterling, is already showing off her athleticism in an adorable video!!!
The Kansas City Chiefs superstar and his wife posted footage of their oldest child's soccer session on Tuesday ... showing off her goal-scoring abilities.
Mom and Dad are happy as can be as Sterling kicks the ball around ... and she even gets creative at one point -- picking up the ball and scooping it into the net.
