I dunno - if I were his mom I wouldn't be happy about an 11 year old playing tackle football either. You being the coach doesn't mean he can't get a concussion. Even the mild effect of head butting the ball in soccer is associated with reduced IQ points. I know you assume this is about your ex wanting to restrict your time with him, and you might be right, but it might also be that she has read about the effects on young brains of the sport. I certainly wouldn't have put him in the middle of it by telling him you could still sign him up.
