The very fact that your daughter knows all about “the guy” and still decided to move in with him, would lead me to question her judgement. I’m not asking does she love and care for her child. You know she does, but addiction to drugs in the early years leaves many people fixated at an immature level. If I were in your position I would put the police on notice. Your brother sounds like a person who has been given many 2nd chances, all to no avail. The safety of your grandchild is of paramount importance. God forbid, if anything happened you would never forgive yourself. Your daughter is also vulnerable and your own recovery has become unstable as a result of all this. Has your brother a criminal record? Why is he taking this sudden interest in your girls? All very sinister and disconcerting.
