The family says that the son loves to help shred bills, but they never expected him to shred actual dollar bills.
The young boy is well versed in how the machine works, often helping Jackee to "shred junk mail and just things with our name on it, or important documents we want to get rid of", she said.
As for Leo, his parents say he's banned from using the shredder anytime soon.

Surprisingly, they may be able to salvage the ruined money after all - there's a United States government agency that specialises in mutilated cash.
The US Treasury Department allows people to mail in destroyed currency, which can sometimes be reimbursed - although this can take up to three years to happen.
