An Endangered Child Alert was canceled after an 11-month-old baby was found safe.
Tennessee Bureau of Investigation officials said the child is missing out of Putnam County on Tuesday.
His name is Mason Nicholson and he may be in the company of his non-custodial mother. Officials say he was last seen at his Cookeville-area home.
He was described as having blonde hair and blue eyes, weighing 26 pounds.
The child was found safe later Tuesday evening.
