I'm a primary school teacher in year 6. I spend lots of time having to deal with pupils falling out with each other on messaging apps/social media outside of school hours. They then bring these issues into school the next day, and there are tears, tantrums and, on some occasions, fights. And staff have to give up lunch hours, break time and learning/lesson time to deal with the fall out. Children can't learn if they are brewing on what's happened the night before, eg falling out with their peers.
Why do parents let their children on social media? The min age for WhatsApp is 16 - it's 16 for a reason! Many primary aged children are not emotionally able to deal with issues via messaging - even as adults we can recognise that tone and body language can play a huge part in communicating - social media and messaging removes that important aspect and if we as adults can get it wrong, why do we expect children to be able to deal with it? It's affecting their mental health.
I've mopped too many tears this week and much of it can be avoided.
