How do those of you who have bio kids & step kids full time disengage from your step kids? I have a ds7 & a dd10. My SO has a ds7 & a dd12. The girls share a room & the boys share a room. I have been partially disengaged from the skids for a while but find it almost impossible to disengage completely, especially when my bios are involved. What do you do when skids & bios are arguing or fighting & SO does nothing or blames your bios? I feel like my bios are always in trouble & his get away with murder & that my bios are beginning to see how unfair it is.
