HANOVER, Pa. — Kaela Dutterer is a head banger.
More than a year ago, her mother, Heidi Dutterer, received concerned calls from her teacher about this behavior in the classroom. Kaela, the teacher said, was repeatedly banging her head against a cement floor.
The calls alarmed Dutterer — not just because she worried for her daughter’s safety, but because the calls, she felt, indicated that Kaela’s teacher couldn’t handle her.
