When you hire a babysitter, you put the care and safety of your child in the hands of another. But would the person you hire know what to do if your child choked or got injured? The truth is many babysitters would not know how to handle those situations. That's why Mayo Clinic is working alongside a national, non-profit organization called Safe Sitter. The Safe Sitter course teaches tweens and young teens how to keep the kids they babysit safe.
