NEW YORK - Four million Bumbo Baby Seats are being recalled due to the risk of babies falling out of them, said the U.S. Consumer Product Safety Commission on Wednesday.

This doesn't mean that parents have to ship the seats back or throw them away. The company is encouraging consumers to order a repair kit that contains a restraint belt for the seat, available for free.

"Consumers should immediately stop using the product until they order and install a free repair kit, which includes: a restraint belt with a warning label, installation instructions, safe use instructions and a new warning sticker," said the CPSC. "The belt should always be used when a child is placed in the seat."

The government agency said there have been dozens of incidents since the October 2007 recall, which required that warnings be added about the risk of placing the baby seats on raised surfaces, like tables, chairs or countertops.

The CPSC said the seats are sold at major retailers including Target, Wal-Mart, Sears, Toys R Us, Babies R Us and USA Babies.
