Welcome to that wonderous roller coaster called "baseball parenting".
My youngest turned 18 today, just started his last high school season, and will be off to play college ball with his brother next fall, at which time the nest will be empty, except for the new dog that has taken up residence at the foot of our bed, in the middle of our bed, on my pillow, across my legs, etc.
It truly seems like only yesterday we were playing backyard games, with his "home run line" at the little tree, and his big brother's line at the bush, and both dressed for little league games hours before they needed to....
Have a ball!
