He's just coming up for 7. Really thought I had a year or more before he'd want to try it out. He's spent all summer playing with local children and he's been enticed away. 
Going to contact the school tomorrow. Anyone know how long it takes to enrol? Term started a week ago and if he's going I want him to not miss too much of the start of the school year.
I think he's going to love it but I'll make sure he knows HE will always be an option for him.
I'll be an outcast in this forum soon. Woe.
