Kansas City, Mo. ? The federal Consumer Product Safety Commission is warning parents and caregivers to immediately stop using a popular brand of bassinet after the death of a second baby attributed to the product. Six major retailers have stopped selling the bassinets.

The warning covers the Simplicity 3-in-1 and Simplicity 4-in-1 bassinets. CPSC spokeswoman Julie Vallese said Thursday the danger is so severe that the agency was compelled to issue the warning late Wednesday ahead of a likely recall.

“Recalls can take time, and the commission felt that time was of the essence and that warning the public about this product was so important that we could not wait until a recall was announced,” she said.

Wal-Mart, one of the largest distributors of the product, said Thursday it is pulling the bassinets off of its shelves and its Web site.

In addition, Toys “R” Us Inc., Kmart Corp., Big Lots, Target, J.C. Penney have also recalled the bassinets, the CPSC said late Thursday.
