Sometimes I think too much, but how fortunate for your son that you have been able to halt this (Newport's words) at an early age. Is it something that will have to be continued to be kept cleaned up, or will cleaning it up when he's this age halt it?
That's what my husband and I were discussing- if these younger kids were able to be cleaned up, it would break the progression and the cycle, wouldn't it?
Newport in all the family/friends you've watched and worked with over the past few years, is everyone affected, or have you found some that are not?
