One of the reasons it happened this way was because the internet made both education and entertainment accessible to them. But back then it was the need of the hour. Now that the world is almost back on track, it's not unusual to expect that your child's phone time is reduced as we're more and more aware about the perils of being chronically online.

One of the biggest side effects of the internet is invasion of privacy, in order to reduce this risk or side effect you need to teach your kids about digital hygiene. And how important it is to be mindful of who they trust with their information. You can also download a VPN so that the data of your household is protected.

Apart from that stress is one of the biggest issues amplified by the internet. In order to keep it at bay it is very important for one to limit their screen time. You can also use this screen time limit to teach your kids about maintaining boundaries within oneself. 

One of the key ways to minimise side effects of literally anything is to realise moderation is the key.
