Each session will still be 1 hour, but for young kids, it'll be best to have it as a pair lesson. We have coached young kids before and we have come to the conclusion that 45 minutes is the max as they do not have a very long attention span but with 2 kids on court it'll be evened out.
Our approach to coaching young kids is to let them have fun. So that they can relate tennis to fun and vice versa.
Our aim is to develop the love of sports in your child and having fun while they learn basic motor skills. To manage your expectations, your child will not suddenly be able to play a game of tennis. Time and patience are heavily required.
