A recall has been issued for the Bumbo Baby Seat as there have been reports of babies falling out and fracturing their skulls. Bumbos are not meant to be used on raised surfaces (although many of us might be guilty of it) and that’s generally how kids hurt themselves by launching out of the seat and rolling off a table.
You can register to receive a free retrofit kit, which includes a belt with a warning label, installation instructions, safe use instructions and a new warning sticker at http://cpsr-rspc.hc-sc.gc.ca/PR-RP/recall-retrait-eng.jsp?re_id=1666
