A report by a San Francisco TV station has prompted the CPSC to open an investigation into the Bumbo Baby Sitter.

The popular Bumbo, which has sold 250,000 units since its debut a couple of years ago, has been implicated in at least three accidents in which a baby has fallen from the seat. In each case, the Bumbo was put on a high surface (table or counter top) and the child toppled out of the seat, to the floor.

In the report, KGO-TV noted that the Bumbo has been marketed to parents for “eye-level feedings”—-and pictures on the Bumbo’s web site showed the seat on tables, counter tops and other high surfaces. Yet the Bumbo comes with a warning label that says “never use on a raised surface.” (Since the TV report aired, Bumbo removed those images from the their site).

A quick search YouTube vidoes of babies in Bumbo seats reveals that many parents are using it this way—on high surfaces. But since the Bumbo has no safety strap to secure it to a table or counter top, a baby can tip and fall out of the seat.

In our book, we mistakenly said the Bumbo could be used on a chair (we based that info on the company’s previous marketing). We regret this error and are correcting our book to reflect this advice:

ALWAYS use your Bumbo on the floor. NEVER put the Bumbo on any raised surface like a table, chair or counter top.
