Halloween // Searching for a short horror film...

I watched a short film quite a few years ago and I’m having trouble finding it again. I’m really hoping someone here can help me! The plot is about a child who keeps asking their mom to check under the bed each night for monsters. The mom checks each night and says something like “nope, no monsters”. The last night she checks there IS something under the bed. I vaguely remember it being a creepy smiling face. The mom is startled but again she calmly says “nope, no monsters” and the video ends. Does anyone know the name of this film?
