I just returned to my hometown and have noticed something with two of my grandchildren, ages 5 and 3 years old, which I haven't seen in 2 years. My 5 year old granddaughter loves to SEE her little brother get spanked to the degree of lying on him, and even enticing him to do things he should do then tell on him. Example: they are not allowed to run in the house, and she will start playing with her brother and chase him. When she hears someone coming, she will sit down real quick and leave him to be chastised. If he is taken to another room she will quietly tip to the door to peek between the crack and watch. I thought she was doing this so I watched her one day when she didn't know I was watching. Some things I have revealed to my son because his wife always sides with the daughter. Since I have been back I have had to correct the mom on how she chastises him, (hit his hand so hard one day until his wrist hurt him for a week, and pushed him in his chest until he fell back, etc. I caught her), and she does this in front of my grand daughter. I threatened to report her if she hit him again. My grand daughter is so creative in what she does to get him in trouble until I fear something is seriously wrong with her. Any advice?.
