The Consumer Product Safety Commission is set to announce one of the largest crib recalls in United States history, involving cribs with dropdown sides, according to several news organizations.

The Atlanta Journal-Constitution reported that the agency will announce a massive crib recall on Tuesday according to a spokeswoman, though she offered few details.

CBS News reported that there is a major push to ban cribs with dropdown sides, which may be unsafe or even deadly for children.

It is not yet known which models will be subject to recall.

More than 4.6 million cribs have been recalled by the CPSC since 2007.

In July, the CPSC recalled 400,000 Drop Side Cribs from Simplicity of Reading, Pa., after finding that faulty hardware on the side of the crib could detach and create a space where an infant could be trapped and suffocate. The CPSC reported the death of an 8-month-old child from Houston who died from suffocation.

This followed a crib recall of 1 million Simplicity cribs in 2007 and 2008, also due to a drop side hazard.

CBS News reported the story of one child's death: 10-month-old Tyler Jonathan died in his crib after getting his head stuck in a gap between the side rail and headboard.

"(The crib is) every parent's safe-haven for their child, and to see the horrific site of him strangled ... was just horrifying to me," his mother, Michele Witte, told CBS News.

The death of 2 1/2-year-old Serenity Bergey in a similar manner is the center of a wrongful death lawsuit in Palm Beach County, Fla., brought against Simplicity by the child's mother.
