Dad Sings Disney Song with His Daughters, Your Heart Explodes with Cuteness

Nurturing children does not mean having serious and flat time all day long. As shown by Jorge Narvaez, a single father from San Diego, establishing a close bond with his little daughters can be so much pleasure. He demonstrates an extraordinary way to interact with his little girls by collaborating in singing A Dream Is a Wish, the soundtrack of Cinderella movie.

Although Jorge had a complicated childhood, but he does not want to share the same boat with his children. He tries his best to keep his daughters, Alexa (11 years old) and Eliana (8 years old), living a joyful life.

This beautiful moment of father and daughters has proven that divorce is not the end of the world.
It is the beginning of real struggle of life, to survive, to think positively, to rise and shine.
