A baby boy decided to join in with his mom for a singalong at their Colorado home, adorable footage posted in December shows.

The video, filmed by Megan Vaughan, shows her singing a note while son Brandon rests on her lap. He quickly gets in on the action and begins to sing along.

Vaughan shared the clip to her YouTube channel, writing that he is the “cutest duet partner.”
