I hope all is well with you. At what age do you work with kids? My grandson is 8 and I have been working with him and the biggest thing is I have got him moving hips and shoulders before he swings the bat. He is the smallest kid on the team and he batted .700 (machine pitch) and made the All Stars. I am thinking if his love a baseball keeps at the same intensity when he reaches 12, I may bring him to you. Im afraid at 8 he wont retain th einfo.
