Not necessarily. Babies can be removed at birth for reasons other than drug/alcohol abuse. One phrase that’s used (IIRC) is risk of emotional harm. Also if a woman is considered generally incapable of adequately caring for a child for any reason (poor mental health, learning disabilities or similar) that can also be a reason for removal.I don’t think this can be true. If she was clean throughout her pregnancy and since birth why did authorities go ahead with an adoption? I’m assuming he was placed in to foster care for the first 9 months of his life in the hope that he could be returned to his birth mother if all was going well with her. For whatever reason she was obviously not in a position to have him returned to her.
If Preston’s birth mother is the woman we think it is, being a notorious teen murderer who has not managed to stay out of prison for long without breaching bail conditions is a pretty solid reason to remove a baby at birth.
