AIBU to ask class parents to withhold phones?

[SarahBcn]

The recent news about UN advising against phones in schools and countries banning them in schools has made me want to take action! My dds primary doesn't allow phones in school, but I know that children do have them as I see them on them after school. Already she has said that a few in her class have them (she's in year 3).
I read about a town in Ireland where majority of parents agreed not to give their kids a phone until year 7 and it's worked. I want to suggest this on the parent's whatsapp group - how do you think they'll respond?

There are few reasons but not zero. My younger children had a phone when their older sibling had one in year six (for walking home) because I’m divorced and they liked to be able to message me on it when they were with their father - jokey every day things so we stayed close. I also travelled for work and they liked to be able to message me. However they didn’t have social media / ways to message friends or even really games on it til high school.

Just FYI @NorthWestThree some DCs with Type 1 diabetes use smartphones and Bluetooth technology to get alerts if their blood sugars are too high or low so that they can adjust their insulin intake accordingly. For this to work, their smartphones have to be with them and on at all times.

So in fact that is a reason to give a child a smartphone.
