A baby or toddler in a bathtub requires a parent's undivided attention. The tub was still filling with water; where on earth was the mother not to notice the water level??
IMO, social media isn't the only issue in this case. Drug use was also involved if the woman was discussing drug paraphernalia on SM. She may have had drugs in her system at the time. IDK. But, I've had drug dealers as neighbors in the past and their lives revolve around drugs--#1 priority in their lives.
A young couple who lived next door to me (didn't look over 20 if even that old) had a toddler. He was about 2 by my estimation, but was very small for his age. One day his dad was looking for the little boy and approached me while I was in my car. I asked if he looked in the back play area; he said yes and I looked around the area for signs of the boy. The young man disappeared for a while, and then returned with the boy from
across the street. Another time, the little boy came to my back door asking for "a piece of bread." I'd seen his mother on numerous occasions unloading groceries from the car, so I knew they had food. I thought the parents were teaching the boy to beg from neighbors so I told him I didn't have anything to give him. In the ensuing weeks and months, I realized the parents were dealing drugs and saw another pattern. There was constant activity next door with people coming and going throughout the day and night. Then, it would be deadly quiet for a couple of days before the activity started again. I later read that some drug addicts (like meth users) go on a 3-day binge where they do not sleep, and then sleep up to 48 hours straight. Then I felt ashamed for not giving the little boy something to eat when he came to my back door, because I realized he was probably going hungry while his parents slept.
Parents cannot give higher priority to anything above their children--whether SM, drugs, boyfriends/girlfriends, etc. In this case, the woman was messaging a neighbor who accused her of stealing a package. If the accusation is true, the young mother may have been stealing to resell the merchandise for drug money. This was the focus of her life, not her children. MOO
