If you own a Storkcraft crib, please read this article from CBC Canada about a MASSIVE RECALL regarding cribs with drop side mechanisms that fail. There have apparently been four deaths in the US and many injuries.
For US residents, please check here.
FYI: The Storkcraft website has been down all morning. I am assuming that its system has been overloaded. If you are using a Storkcraft crib, keep trying the website until you can get on, then order the replacement kit asap!
