It is no secret that babies can't talk and of course this makes them extremely difficult to communicate with.

But did you ever stop to think that perhaps there are other ways in which you can talk with an infant without uttering words?

Well, one awesome grandma found a way to chat with her 9-week-old granddaughter, Aria, using sign language!

Shari Joy McMahon shared a video on Facebook which shows her deaf mother teaching the baby how to sign and it is the most adorable thing you'll see today.

The heartwarming moment was posted on the Love What Matters page and has since been watched by over 4.2 million people.

Watch it for yourself and see why the clip has garnered so much popularity.
