Baby’s hilarious reaction to his own fart

The parents of a two-month-old baby boy shared a video of the little cutie pie on social media.

Little Mareto from Japan can be seen in the video smiling innocently at the camera.

He suddenly lets out a loud fart, that not only surprised his mother, but left him stunned as well.

Judging by the look on his face, baby farts smell just as bad as adult ones.

Mareto’s mother could not stop laughing, and it seems he was just as a mused.

Yes, mum, it’s all fun and games until he grows up and starts leaving stink bombs in his wake just for laughs!
