My 3 year old son recently started Playball and he loves it! His face lights up whenever he knows its playball day and always throughout the week wants to play the games that Andy (playball teacher) had shown the previous lesson. Andy is fantastic and very patient with the kids even when they do misbehave sometimes.
Playball is a great way to introduce your child to all the different ball sports so they can get an idea of what they would be wanting to do more of later on. Its in a controlled environment undercover, I highly recommend!
