The South African company behind Bumbo Baby Seats is recalling nearly four million seats in response to scores of reported infant injuries including two dozen cases of skull fractures. In a second blow for the product, the Consumer Product Safety Commission has found that babies can too easily wiggle out of the floor seats leaving themselves vulnerable to injury. The news follows a previous warning that the seats were dangerous if placed on raised surfaces. About 1 million of the molded foam seats were recalled in October 2007 for additional warning labels against placing the Bumbo seats on tables or kitchen counters. Since the first recall, CPSC and Bumbo International of South Africa have learned of at least 50 incidents in which babies fell from Bumbo seats while they were being used on raised surfaces. CPSC says another 34 babies fell from the seats while they were being used on the floor or at an unknown elevation. In all, there were 21 reports of skull fractures to infants. Consumers are asked to stop using the seats and contact Bumbo for a free repair kit that includes a restraint belt and instructions on how to safely use the seat.
