'No longer an only child': boy has the sweetest reaction to mum's pregnancy announcement

There's nothing better than growing a little family, especially if it's been a long and difficult process. 

An anonymous dad recently posted to Love What Matters with the cutest video of his nine-year-old son, realising that he's going to be a brother for the first time. 

The video is adorable, and made even better by it's uplifting backstory: 

The couple has their first child, Blake, when his mother was 18 and the father was 20.

Because they were young and not married, the couple decided to take things slow "to ensure we would have a happy and healthy family." 

"As our son, Blake, grew older and we became more financially stable, we knew it was time to grow our little family." 

But the couple encountered fertility problems, and were unable to conceive another child, or so they thought. 

Throughout their fertility problems, they were open and honest with their son: 

Since he was now nine, it was easier to explain and have him understand. Fast forward to November 14, 2017… We were blessed to share the exciting news with Blake. It is a moment in life that not one of us, will ever forget."

His reaction is perfect, at first he thinks that they are adopting. But his face drops when his mum utters the words: "I'm pregnant" 

He runs to her and starts crying with joy. Our hearts can't take it, and neither can the Internet: 

We have a feeling that he's going to be a fantastic big brother!
