Overcome With Emotion: Beautiful Baby's Tears As Mum Sings To Her

Baby's Emotional Reaction to Mother's Song

This video is so beautiful it has reduced this grown man to tears – just as its baby star does to her mum's singing.

Ten-month-old Mary-Lynne goes through a full spectrum of emotions as her mum Amanda sings her a rendition of Rod Stewart's ballad My Heart Can't Tell You No.

At the beginning of the video – which has been viewed nearly 5 million times on YouTube - Amanda asks: "Do you want mummy to sing a song? Let me know how you feel about this song."

As she begins to sing, Mary-Lynne looks confused and then breaks into a wide grin as the song continues. But her eyes quickly fill with tears, and she starts to quietly weeps.

Throughout the song, tears silently roll down the baby's cheeks as she looks up at her mum.

Once Amanda finishes and says 'It's just a song', Mary-Lynne then laughs happily.

One viewer: "Absolutely beautiful! She is precious. I remember doing something similar, but I wasn't as young as ten months, probably more? like two years.

"My mom would sing me lullabies in bed and I would just cry and cry because I was overwhelmed by it all."
