I agree, age appropriate talk about sexed bodies, penis = boy and vulva = girl but clothes, games, toys, activities someone likes has no impact on sex and though many girls seem to like x there will be lots of girls who don’t etc
Also no smart phone until secondary and then use parental controls to prevent social media. Having learned lessons with my oldest the next one doesn’t have Tiktok, Instagram or WhatsApp. I caved on Snapchat but wouldn’t again. Yes it does mean some friendships don’t work out as a result. My observation is that it has turned out to be the friendships which I would find quite unhelpful which haven’t worked out. Good friends aren’t so superficial as to judge other children on what social media they are allowed.
This wasn’t even a thing in Junior schools pre pandemic from my experience- it has grown fast. Doesn’t seem to be in infants/primary in my area. I do think social media has a lot to do with it. Social media is harmful to children for reasons of safeguarding, dangerous ideologies, eating disorders, low self esteem and the compulsive nature of it. Children will absorb values from social media which may not reflect the values of their parents, family or culture. I am sure that social media culture such as being hyper judgmental, excising anyone with different opinions, ruthless banning, blocking and deleting manifests as intolerance for those with different opinions in real life and the current problems with cancel culture. Equally harmful to children is all the things they stop doing when they are focusing on social media.
You stop children being sucked into tiktok and Reddit by making good use of parental controls, starting as you mean to go on with monitoring and restrictions on screen time, modelling good phone hygiene yourself, for example, leaving phones downstairs over night, not letting social media become addictive for you, whatever you think is a healthy way of managing your phone use.
It can also help to talk to your children about the compulsive nature of social media platforms and how hard people find it to put their phones down and do something else, how social media can make people feel bad about themselves sometimes, how people can sometimes see really upsetting things accidentally and how bad people can use it to frighten or hurt others, so that children understand that you are choosing to protect them by not letting them have it rather than just ruining their fun.
The pressures just keep moving younger and younger. My oldest didn’t really know what social media was until secondary school my youngest heard about it from friends who used it probably in year 5 or 6. Now children are hearing about friends using it in infants. Our children are all still Guinea pigs with this technology. I very much doubt any parents regret keeping their children off social media for as long as possible! Until 16 if you can manage it. I do think at some point the age limit for all platforms will be raised to 16.
