"Until she sorts herself out?"
I understand you would not be here, if you did not realize there is a problem, but she simply CANNOT "sort herself out." Addiction is a very complex disease. do not think for one minute that the child comes first in her mind. As long as she is actively drinking, booze is the # 1 priority of her life.
Please, please, please, seek immediate SAFE child care for your precious little one. She is currently unfit to provide for her own child. She cannot be trusted to meet the child's needs and everytime you leave that child in her care you are playing a game of russian roulette.
We are here for you.
