The largest crib recall in history is under way. Parents of the babies who died want others to pay attention to the danger.
Michele Witte's 10-month-old son Tyler died when he became trapped in between the side of his crib and the mattress.
"That is every parent's safe haven for their child, and to see the horrific sight of him strangled was just horrifying to me," she said.
A New York father lost his 6-month-old son five years ago.
"That was the thing; there was never any warning about these cribs," he said.
Now 2.1 million Stork Craft brand cribs are being recalled.
But it's not just that brand. Safety advocates are warning about all cribs with drop sides, especially hand-me-downs or cribs that have been taken apart then reassembled. They say the hardware can get loose and end with deadly consequences.
