It is the video that will put at your heartstrings like no other - a baby girl moved to tears as her mom sings to her.
In the video, 10-month-old Mary-Lynne Leroux reacts to her mother, Amanda, singing the song "My Heart Can't Tell You No."
At first little Mary-Lynne smiles, then her eyes well up - and a single tear runs down her cheek.
It just gets more emotional from there.
This is one video you're going to want to watch.
