LW says "I also think if he wasn’t scheduled for weekend activities he’d become more independent" which is such a weird and wild opinion that I really wonder what, exactly, she and Husband do with their own kids on weekends.

(This is not a comment about not signing your kid up for extracurriculars, it's the bizarre way that she links "weekend activities" with "this kid is too dependent and sometimes tells me when his sister breaks [what he perceives as] the rules".)
