The newest viral video sensation on YouTube stars an emotional 10-month old baby, brought to tears by her mom’s rendition of “My Heart Can’t Tell You No,” the 1988 Rod Stewart hit. Cheerful before the singing starts, the baby girl gets visibly more emotional as the singing continues. The mother, Amanda, stops her performance before the song is finished because of her daughter’s reaction. As she hears upbeat, comforting words once again coming from her mom, the baby lets out another giggle. The scope of emotion from this sweet little girl is exactly why it has received nearly 5 million views in the past 12 days.   What are some of your favorite adorable baby videos on YouTube?
