Angel Care monitors are recalled in Canada and the US. Looks like you can get a fix for the cord.

The cord that attaches to the baby monitor’s sensor pad placed under the crib mattress to the baby monitor unit, can present a potential strangulation hazard if the child pulls the cord into the crib and it becomes wrapped around the neck.
