Grandmother and baby are both deaf, but they've found the perfect way to communicate

Pamela McMahon shares a pretty unique bond with her four grandchildren, a bond that no one else could break.

They’re all deaf.

Pamela took the time and taught all her grandchildren how to sign from a very young age. 

And when Pamela’s daughter Shari Joy gave birth to her first child, granny was about to have the same unbreakable bond for the fifth time.

Baby Aria was also pronounced 100 percent deaf, and at a mere nine-weeks-old her grandmother Pamela began to speak to her through signing.

Pamela’s daughter Shari decided to record the encounter, and we’re so glad she did.

The video shows Aria smiling and pulling some seriously cute faces as her grandmother speaks to her through signing.

And it's obvious the baby is enjoying the conversation just as much as her grandmother. 

Looking at how content Aria is with her grandmother, we bet Pamela is going to get all the good secrets.
