This little girl with a prosthetic leg had the sweetest reaction to a very special doll

As many little girls would be, Emma from Texas was very excited when an American Girl doll arrived for her in the post,

But this wasn't any old doll - this was one was just like her.

Emma has a prosthetic leg and her mom, Courtney Fletcher Bennett, wanted her to have a toy that she could relate too. With the help of A Step Ahead Prosthetics, she sent the doll off to the American Doll company to have a mini prosthetic leg - in Emma's favourite colour, pink - fitted, as a surprise for Emma.

And her reaction says it all.

"You’ve got to be kidding me,” Emma said as she opened the box. “It has a leg like me!”

A letter from the company reads:

“After a few weeks of training, she is ready to go home and lead a life without limitations with you.”

Stop it, you're killing us.

The video has been watched a whopping 8 million times so it seems Emma's overwhelming joy is going to spread.
