This mom wanted to check her son's reaction to the thought of banging his head, so she attempted to prank him by pretending that he banged his head by bumping her fist on the wooden cabinet. She expected him to either cry or throw a tantrum. However, she got caught by her toddler as he figured out that he didn't hurt his head, and his mom had made the banging sound off her fist. He hilariously imitated his mom and made a similar sound to show his parents that he knew what was happening.
