Our Future Soccer Star!!

We new we wanted Chase to get lots of outdoor activities for his birthday....he did, but Daddy really wanted him to have a real soccer ball and a goal. Chase is learning really fast. He's getting pretty good at kicking! Next year, we plan to sign him up for soccer....you have to be 3, so hopefully sign-ups are after his birthday. Then the debate will be which number on his jersey #3 (like Mommy) or #4 (like Daddy). Should we do a coin toss or Rock, Paper, Scissors?
