The heart stopping footage of a two-year-old saving his trapped brother.

Heart-stopping footage captures the moment a clever two-year-old rescues his twin brother trapped under a chest of drawers.

In the video shot on a webcam in the toddlers’ bedroom, Bowdy is seen lifting the large piece of furniture off his crying brother, Brock.

The footage, later posted online by the boys’ parents, shows the two boys climbing on the chest of drawers before it topples forward.

While Bowdy appears unharmed he sees that his brother is trapped beneath.

It takes the little boy a few attempts to rescue his brother as he tries to figure out how to free him, but soon lifts the drawers just enough for Brock to wiggle free.

Parents Ricky and Kayli Shoff from Utah in the US said they posted the video online to bring awareness to the dangers of unsecured furniture.

“I’ve been a little hesitant to post this,” Mr Schoff wrote in a Facebook post on Sunday.

“But I feel it’s not only to bring awareness, but it is also incredible. We are so grateful for the bond that these twin brothers share.

“We know Bowdy was not alone in moving the dresser off of Brock. And feel blessed that he is ok.

“Please make sure all your dressers are bolted and secured to the wall. Please share.”

The video, also posted on Youtube, has drawn a mixed response from social media users and other parents - some criticising the couple, with others expressing sympathy and praising Bowdy's courage.

"Omg! I'm glad he is ok! It's such a frightening thing to watch or see..." one commenter wrote on Facebook.

"It is clear who will star in the upcoming Marvel super hero movies. Staying calm and being able to make sound decisions is something only for the great," commented another.

"Wouldn't you think that you would have heard the dresser fall and go to investigate?" questioned one Facebook user.

The Shoffs' aim of spreading awareness seems to be right on track though, with the Facebook post gaining more than 2000 shares and the YouTube clip viewed more than a million times in two days.
