Firm Recalls 100,000 Portable Playpens: The products, manufactured by Baby Trend Inc. of Pomona, have been voluntarily recalled after one type collapsed at least four times, killing two babies, the Consumer Product Safety Commission said. Two other babies were revived after they stopped breathing when their playpens collapsed. Unless the rails of the playpen are locked, a baby can be caught by the neck and strangled. The names Home and Roam, Baby Express or Baby Trend appear on two of the four top rails of the playpens, which were sold from 1992 to 1994 by retailers including Kmart. Consumers can call (800) 234-1879 to have the top rail lock replaced free of charge with a lock that is designed to prevent collapse.
