Instagram is adding a new alert for the parents of teen users of its social media platform. The network will alert the adult if their child repeatedly searches for terms about suicide or self-harm in a short time frame. From that notification, the parent will optionally be able to access resources for having conversations with their teen about these topics. These alerts will begin rolling out for parental supervision users in the US, UK, Australia and Canada next week, with later regions to be added in the future.
