Tammy made an appointment for her and her husband to meet with CPS on August 10. But first thing that morning, she took her son to the pediatrician."She examined him—she's been his pediatrician since he was six days old," said O'Haire in an interview. "She confirmed it was a birthmark and not a bruise." The doctor even wrote a note.

What's more, O'Haire has posted Facebook photos of her son every month on his birthday. The birthmark showed up at around five months. She had four time-stamped photos of this "bruise."

At her CPS appointment, they were joined by a sheriff. O'Haire showed them the photos and the doctor's note. The sheriff's response?

"The sheriff told us that he thought the birthmark looked like a handprint," O'Haire recalled.

"These stories illustrate the fact that we must kill off the notion that overreacting to nearly non-existent threats is prudent. As one parent wrote in support of the day care provider on the provider's page, "I would rather see 1 million reports that end up not being an issue than see even one go unreported and lead to serious injury or the death of a child." We have to stop framing the issue like that. If the system is reporting one million unfounded cases, that is a million distraught families. This is not something we have to just shrug off in the name of child safety. We cannot allow hysteria to trigger government involvement."
