For the purposes of the debate, (a) there are two approaches in raising children around the use of electronic devices and access to the internet, (b) children are defined as individuals under the age of 16.
Approach A is supervisory. Parents following Approach A allow their child to have electronic devices and independent access to the internet, but will supervise their child's activity through mediation measures (e.g. talking to their child about the websites, content, or functions they should and should not be consuming).
Approach B is authoritative. Parents following Approach B do not allow their child to independently own an electronic device (e.g. the child must ask their parent to use their phone or tablet and return it once done) and do not allow unrestricted access to the internet (e.g. the parent will impose controls to block certain websites, content, or functions).
