• The Consumer Product Safety Commission is warning parents their children could be at risk of death or injury while using Baby Trend's Sit N' Stand Double and Ultra Strollers.
• A 14-month-old child was killed after it became entrapped in the stroller and a 17-month-old was injured, the safety group said.
• The strollers have been sold nationwide since 2009 and are available at major retailers including Amazon, Walmart, Target and Buybuy Baby.

A baby was killed and another was injured after they became entrapped in a popular Baby Trend stroller that's sold at retailers like Amazon, Walmart and Buybuy Baby, the Consumer Product Safety Commission announced Thursday. 

The safety group and the company issued a warning saying children could be at risk of head or neck entrapment in Baby Trend's Sit N' Stand Double and Ultra Strollers if they aren't properly strapped in or, a child climbs on the exterior of the stroller. 

A 14-month-old child who wasn't sitting in the stroller was fatally asphyxiated after its neck became entrapped in the space between the front of the canopy tube and armrest of a Baby Trend Sit N' Stand double stroller, the CPSC said. 

The child's father was nearby but unable to see the kid, the group said. 

The other child, a 17-month old, was partially secured in the stroller and became entrapped in the space between the back of the canopy tube and the seat back of the front seat, resulting in neck bruises, the CPSC said. 

The strollers have been sold nationwide since 2009. It's unclear when the incidents happened or whether there have been other cases. 

"Baby Trend and the CPSC agree that Sit N' Stand Double and Ultra strollers with detachable canopy are completely safe when used as intended and in accordance with the company's operating instructions," a company spokesperson said. "This tragic and exceedingly rare accident could have been altogether avoided if the young toddler had not been permitted to climb and play on the stroller, which was not being used as intended at the time."

However, after Baby Trend issued its statement, the CPSC said it was inaccurate for the company to say the CPSC considers the product to be "completely safe."

"We are disappointed that Baby Trend issued a clearly inaccurate statement asserting that CPSC 'agree[s] that Sit N' Stand Double and Ultra strollers with detachable canopy are completely safe when used as intended and in accordance with the company's operating instructions,'" the safety group said Friday.

"CPSC does not make determinations that products are 'safe'. The warning agreed to by CPSC and Baby Trend instructs consumers to remove the detachable canopy when the stroller is not in use and not to allow children to play on the strollers. The warning also instructs consumers to fully secure children in the stroller using the five-point harness when the stroller is in use."

The impacted strollers have model numbers beginning with SS76 or SS66, which can be found on a sticker on the left inside rear of the frame. 

Baby Trend is a global manufacturer of products for children that's been in business for more than 30 years, according to company news releases. In 2016, it was acquired by the Alpha Group Co. Ltd. for $94 million. 

The Alpha Group is an animation and pan-entertainment platform based in China that started as a toy company.
