The government has announced the recall of more than two million cribs and is warning parents to stop using them immediately. Rebecca Spitz has the details.

UNITED STATES -- Late Monday, the Consumer Product Safety Commission said it was recalling more than two million drop side cribs. Specifically models made by Stork Craft Manufacturing, a Canadian company that also sells cribs carrying the Fisher-Price logo, after four suffocation deaths and dozens of cases of babies getting trapped or falling out from the cribs.

Regulators found the drop sides to have faulty plastic hardware and are now telling parents to stop using these cribs immediately.

"Basically what happens is the top of the drop side remains attached to the crib, but the bottom becomes loose so that there's a gap at the bottom of the side so that the baby can literally roll off of his mattress and become entrapped in the space between the bottom of the side and the mattress and suffocate," said Diane Dubrovner of Parents Magazine.

The CPSC says incidents include 15 entrapments, 12 of which were in the U.S. and three in Canada. Four of the entrapments resulted in suffocation.

In a prepared statement, the agency said injuries related to the recall, "Ranged from concussion to bumps and bruises. The cribs involved in these incidents had plastic drop side hardware that had broken, missing or deformed claws, connectors, tracks, or flexible tab stops; loose or missing metal spring clips; stripped screws; and/or drop sides installed upside-down."

While this is the largest recall of its kind, parenting experts say crib recalls are not uncommon. Experts say there've been 19 of them since 2007, 75 percent having something to do with drop side cribs.

Stork Craft is supplying free kits with new hardware parents can put on the crib to make it safer, but in the meantime...

"You should not let your baby sleep in that crib and you should find a safe sleep environment for your baby and that doesn't mean bringing your infant into bed with you, it means using a bassinet if your baby is small enough, using a travel crib/pack-and-play for your baby to sleep in until you know that your crib is safe," Dubrovner said.

To receive a repair kit, parents can call Stork Craft at 877-274-0277 or visit www.storkcraft.com. The recall only involves cribs that utilize plastic hardware and the one-hand, drop side system. Regulators are urging parents not to try to fix the recalled cribs on their own without the kits.
