It's your bad judgment that attributes the death of this boy to his mother's negligence.
You're welcome.
A parents job isn't to gratify every wish, it is to care for and protect a child.
At my church there are 2 boys with issues. Mom and Dad bring a backpack with edibles for them. The boys know not to eat anything that their parents haven't given to them.
It is a tragic circumstance but Mom dropped being vigilant just once. You can't do that.
