This is one of those rare and beautiful moments when you feel a world of emotions but are still rendered speechless.
A video posted on YouTube shows the exact moment when a seven-week-old baby heard and reacted to his mother's voice for the first time. Captured and shared by proud father Toby Lever, the video has already gone viral with over 7.5 million views.
Baby Lachlan, now two-years-old, was initially diagnosed with having moderate to severe hearing loss in both ears.
The video shows Lachlan receiving his first hearing aid. You can see the baby going from tearful bewilderment to smiling wonder in a matter of seconds.
Mere words cannot describe the beautiful reactions that follow. "We cried from happiness," it says in the descriptor for the video. And we're sure watching the video will overwhelm you as well.
Like we said, some things need to be felt and this most definitely is one of them.
