First of all, the child isn't a teen. According to the story, he's 7yrs old.

Second, as I said, the fear of harm to herself and her family as this boy got older was understandable.

What's NOT understandable is how she handled it, by literally sending back a child who is for all intents and purposes, her son; and pinning on him a note stating she no longer wishes to parent him. What she's also stating is that she really doesn't care what happens to him, long as he's out of her hair.
