Congratulations to you and yours!
I always feel sorry for the child when the mother is on drugs as it is like her drugs is more important than her child along with the grand parents as it is difficult being a grandparent and trying to raise the child at the same time but I realize that you cannot say no to your grand child. My grandparents mainly raised me as my step-mother is and was an alchoholic and my.Mom passed away when I was 7y/o, my step-mother told me one time that she did not want any more kids to raise but my sister was okay because she was 13 y/o. Along comes my niece with her two kids and one of them was my step-mother's favorite, he could do no wrong, my .Dad did not care much for him very much before he got alzheimer's and passed away w/pneumonia, anyway to make a long story short she raised my step-nephew and my niece would go to her house everytime she needed something or got out of jail and he has been at a outh authority for two years, almost about ready to get out and go back to my step-mother's, my niece is there, buying my stepmother bottles of booze and she is 85 y/o, I called her one time and she was telling me what a great kid he was and my step-niece is taking good care of her even though she is buying her booze, I just laugh, eventhough I know it is sad as my step-niece is a druggie and the other step great niece that she sort of raised and she was pretty mean to will not talk to her and she has a job and is going to school as she calls me and tells me quite a bit, I tried to adopt her once, along with some of my other family members. I guess I should stop venting.
