Bumbo International of South Africa recalled about 1 million “Baby Sitter” seats after 28 reports of babies falling out of the seats, including three skull fractures, a government safety group announced Thursday.

Babies are at risk for serious head injuries when the seats are placed on a table, countertop, chair or other raised surface and the infants arch their backs, possibly causing them to flip out of the seats and fall onto the floor. The Consumer Product Safety Commission advised that consumers never use the seat on a table or elevated surface.
