A girl with a prosthetic leg cried tears of joy when she received a doll that looks just like her

Meet Emma Fletcher Bennet, a young girl with a prosthetic leg who recently opened a surprise gift from her parents: an American Girl Doll that had been fitted with a prosthesis just like hers.

Emma's mother captured her daughter's emotional reaction and posted the video to Facebook. So far, it's been viewed almost 9 million times. 

The gift was made by  A Step Ahead Prosthetics, a company that customizes dolls for children who have lost limbs.

Even better? They do it free of charge.
