The only benefit I have seen to kids wearing smartwatches is the ability for mobile payments with their watch for the bookfair or other fundraisers. Phones are not allowed at my school, but wearable tech is. Kids usually don’t care about step counting, sleep tracking, or setting alarms and reminders. Honestly, a kid wearing a watch that doesn’t know how to use it and has an alarm going off every ten minutes is frustrating. As far as communication, I feel like that should be discouraged during the school day. Smartwatches end up being a distraction more than a benefit in most cases. Personally I would be more on board to getting a basic flip phone than a watch for emergencies. If you do get a watch, I would explore different parental control features and “school mode” to see what it offers.
I got these almost every morning when I was pregnant. Thankfully they only lasted a few minutes (besides a soreness for the rest of the day), but they sucked. I had to train myself to not move my legs in my sleep.
