My 10 year old has played soccer, basketball, football, and baseball. His first experience with playing on a team was when he was a month away from being 3 years old. We signed him up for soccer. Of course at almost 3, he had different ideas about trying to kick a ball into a goal. He'd sit on the field, gaze up at the sky, and play with the grass.
Now that he primarily plays only baseball by his choice, his skill level has grew by leaps and bounds. We enjoy watching him play and socialize with his team.
He's come a long way from then.
My 8 yr old is my artistic child. Into painting, drawing, crafts, and dancing. She's played soccer, was part of a cheer squad, and has taken gymnastics, but dancing is her passion. Here are some of her at her hip hop dance class.
Our 3, almost 4 yr old had his first experience being on a team this past Fall. He played Tball and was on the Tigers. It was a great way to teach him the basics of the game, since he always says he wants to play baseball like his Daddy and his big brother.
