I currently have an 11 and 10 year old who don’t have phones, so caveat this all with the fact that we haven’t yet hit this stage yet .
However, I was speaking to my sister who is relatively strict (sensible) with her 13 yo DS phone use. So no social media, no phone in bedroom etc. This just seems like the totally logical and sensible approach to me. She was telling me that she keeps his phone in their room overnight and it’s pinging and ringing at all hours.
With most things I can comprehend that people make different life choices / parenting decisions. But this is one thing I honestly can’t get my head around and I’m genuinely curious why people let their kids have free reign on smartphones when they’re clearly so bad for them.
