Parents, listen up. The biggest crib recall in US history is underway. Stork Craft Manufacturing is recalling more than two million drop-side cribs. About 150,000 of them carry the Fisher-Price logo. The cribs are linked to four infants that suffocated. There has long been safety problems with so-called drop side cribs, a side that lowers to allow easier access to a baby. Parents are urged to stop using the cribs until receiving a free repair kit from Stork Craft.
