According to accumulated data, more than 30 infants have died in the US in the Fisher-Price Rock and Play sleeper. Growing concern about product, sold first in 2009, has caused the US consumer authorities to issue an urgent recall. Most of the babies were over three months and died when they rolled over and smothered in the vibrating sleeper. The same product is sold in Canada but regulations say it can only be used as a soother, not for unattended sleep. Just how this is policed seems elusive. It’s purpose is to make the infant go to sleep. Health Canada wrote to Mattel Canada in 2011 with concerns about the product, referring to Safe Sleep recommendations from Health Canada, the Public Health Agency of Canada and the Canadian Pediatric Society.
