LOL...Little Eddie a thug ?  no way !   
 
  
I can share in your pain as a dad....When we first got Cheri and she got big enough to race around with toys that HAD been only Chanel's....my little angel turned into a Gang-Girl and would jump Cheri to get the toy back.... 
Eventually...they reached a truce...and Chanel 'let' Cheri play with the itty bitty toys only...then gradually....she was 'allowed' to play with bigger toys...till in time...Cheri can now 'touch' any toy she wants  
 
  
It was FUNNY to watch and now each plays with whatever they want...anytime they want ....with only the occasional 'stealing'...then they play-fight and kiss to make up....
