Watch terrifying moment dresser falls on 2-year-old boy — and what his twin does to rescue him

Within a few seconds of the start of the bedroom surveillance video, your stomach begins to churn.

Just two toddler boys doing what toddler boys do in the morning — climbing on either side of a dresser in their footy pajamas, shimmying their way to the top.

But as their collective weight rises higher on the front of the dresser, it happens: The dresser falls forward and crashes to the floor.

Two-year-old Bowdy Shoff manages to escape the impact of the dresser, easily pulling his feet out as he sits in front of it. But his twin brother Brock isn't so lucky; he takes the full weight of the dresser, and his head and upper body are trapped underneath.

Their mom, Kayli Shoff, told NBC News her sons woke up early Thursday morning, and she didn't hear the thud of the dresser or any crying in their Orem, Utah, home.

"And that was the weird thing, because I always hear them cry or scream," she told the network. "We also had family staying with them and their room was right above Brock and Bowdy's room, and they didn't hear anything, either."

As his still-trapped brother manages to wriggle his head from under the dresser, Bowdy Shoff at first takes an unfortunate trip back over the dresser, which presses more weight on Brock. There's no sound on the video, but Brock's crying face is clearly visible.

Then Bowdy soon figures things out.

"If you watch the video, I think he stops for about eight to 10 seconds and kind of analyzes the situation: 'My brother's crying, he's hurting, how can I help him?'" Shoff told NBC News.

With that, Bowdy tugs at the dresser.

Then he finally pushes it far enough horizontally where Brock can roll over and escape its weight.

Kayli Shoff told NBC News that perhaps up to seven minutes had gone by before she saw on the baby monitor that the dresser was on the ground. She then ran to their room not knowing if they'd been injured, the network said.

She and her husband Ricky Shoff only found out what happened after reviewing the video.

"My heart sank," Kayli Shoff told KUTV-TV. "I didn't know what to do. I felt like the worst mom in the world."

The boys immediately were taken to the pediatrician and declared just fine, she told NBC News. Dad then bolted the dresser to the wall, took the knobs off so the boys can't climb up and put latches on the bottom drawer, Kayli Shoff added to the network.

NBC News said the dresser is made by Ikea, which last month agreed to pay $50 million to families of three children killed after dressers fell on them. The dresser came with wall anchors, the network said, but the Shoffs didn't install them, thinking they weren't needed.

More from NBC News:

Tipped furniture is a leading cause of death among kids, with one child dying every two weeks because of items such as dressers, TVs, or appliances landing on them and crushing their windpipe or striking them in the head, according to the Consumer Product Safety Commission.

"I think we've made a big impact on people wanting to secure their dressers," Shoff told the network. "You need to tie your dresser down today because honestly, if you wait a day or two, you're just not going to get it done."

This week things seem back to normal for the rambunctious boys — but Shoff said she believes there's a stronger bond between them.

"I really saw it come to play just in this act of love for a brother, a twin brother," she told KUTV.

"We are so grateful for the bond that these twin brothers share," their dad wrote in a Facebook post which included a partial clip of the dresser incident. "We know Bowdy was not alone in moving the dresser off of Brock. And feel blessed that he is OK."
