No phones forever.
OK, not really forever. But my fourth grader claims she is one of the only kids in her class who doesn't have her own phone. That's fine. I don't care if her classmates think she's uncool for not having something I didn't get until I was in college. I don't plan to wait that long to give her a phone, but I don't see why she needs one right now. If I can keep her away from social media, and potential online bullying or child predators for longer, then I'm doing it. The only reason she would need a phone is to contact me in an emergency, and there are other ways for her to do that, like via a smart watch.
