The Internet is part of our daily life and even the smallest children have access to countless content, initially through the devices of their parents / siblings and, later, through their own devices. From the moment parents allow their kids access to the virtual world, they should be aware of the importance of being involved in the use of such devices by children , establishing appropriate rules and being vigilant to signs indicating a negative effect of that use on their behaviour and development. The Internet being a gateway to the world, anything can happen from the moment it is opened. Just as you don’t allow young children to stay alone at home or walking the streets unattended, before they gain the confidence to do so, the same should happen when navigating the world online.
