I knew a child who was baptized at the age of 7. This child answered fluently at the meetings, was conversant at the doors, kept up on her own return visits, could explain anything in the current literature to anyone who asked. This child didn't need anyone to prompt her, the knowledge was her own. She was a great little kid, well-behaved, a joy to be around, the youngest of five children being raised in a one-parent household (all the other kids were just like her).
When the child was 8 she ran away from home. There followed a huge custody battle, and when it was over the child was taken to another state to live with her dad.
I met up with this child again when she was 14 and in legal trouble. I saw her several times in the course of a few weeks. It was obvious that she was no longer living as a JW so one day I asked her what had caused her to change.
Her sincere response was "When I was seven and a half I found out I could do bad."
Was her baptism the result of an informed decision?
