Mix in the more difficult drills with little basketball games that the child likes. Sacrifice what might be a short time growth in skill for a lifetime of improvement because he/she will develop a true love for the game of basketball.
When doing basketball shooting drills don’t let your child shoot outside their strength. What I mean by this is if they have to throw the ball with all their strength and launch it from the hip they are too far out. Get them a smaller ball, lower the hoop, and teach them the right form. Too many kids develop bad form when they are little for the simply fact that they aren’t strong enough yet. The distance will come as they get older.
