My oldest daughter was not my husbands and the other two (girl and boy) were. I believe he treated the girls (his or not) differently then our boy. I know that step or not the kids know how to play one parent aginst the other if they know they disagree on something. Just my experiance and food for thaught. Oh, I want to add your kids sound like typical kids and not leaning twords defiance as far as self destructive I say Yay!!!!!!!!!!!!!!!!! That is awesome!!!!!!!!
