Carol Dianne Benjamin, a mom of two from Madison, GA, has always wanted the best for her daughter Scarlet. But after she was born premature, Carol knew that the road to recovery following a few complications was going to be long for her little girl. However, at 11 months old, Scarlet's life changed forever when she got her very first hearing aids [2], and her reaction to her big sister's voice is absolutely everything [3]. Carol shared the touching video to Facebook on Jan. 10, and it's since gone utterly viral.

"As everyone knows, when Scarlet was born she was three months early," Carol captioned the clip. "She ended up getting [necrotizing enterocolitis (NES)], a certain stomach infection, and the antibiotics that she needed cause hearing loss."

Although Scarlet had a rough go early on, her mom thought she could hear fairly well. It wasn't until Scarlet got her hearing aids that Carol realised that wasn't the case. "It has been a LONG and emotional experience," Carol confessed. "She reacted to most sounds [4] so we thought she could hear fairly well. After what I witnessed today, it was not as well as I thought. Hearing aids make a WORLD of difference!"

So far, the sweet video has been viewed 161,000 times and has racked up more than 1,000 reactions on Facebook. And it's easy to see why: Scarlet's baby giggles will warm your heart right up!
