"It was a joke between the three of us. My sons and I horseplay rough," Wolf said. "We stuck his head in the toilet and flushed it. And my older son was recording it."
Wolf said she sent the video to the boy's babysitter.
"I sent it to her as a joke, like, 'Haha. This is the new way you can discipline them,'" she said. "So she sent it to my boyfriend's ex, who sent it out and made it go viral."
Wolf said her son was never in danger.
"His head was never under the water, his face never got wet. It was maybe the top or this part of his hair," she said. "It's scary to think I might lose my children over this -- over a joke that we played."
Many of the Facebook users who commented on the video said they reported the incident to the Leesburg Police Department.
"The police actually came on Saturday and stayed on the road because people were threatening to come here and kill me," Wolf said. "They have been patrolling the area."
The Florida Department of Children and Families said Sunday that it is investigating the incident and is working with the state attorney's office to determine whether charges should be filed.
"It was just a game," Wolf said. "I didn't inflict harm on him. He didn't have any bruise or cuts. He was laughing during the video."
She said she regrets the stunt.
"Everybody just stop Facebooking me and telling me you want me to die," Wolf said. "I get it."
