I’m not gonna be a Luddite and say smart phone bad. However, you seem concerned so I’d recommend locking it down as much as possible if you want to keep them off stuff like TikTok or Xitter.
As an anecdote, having a smart phone made school much more tolerable since it let me watch TV during lunch, browse memes when waiting in awfully long lines daily, and being able to listen to music when allowed was awesome. They’ll definitely be grateful for one, just gotta make sure it’s not abused.
Also, they’re going to need to be acquainted with the little computer in their pocket eventually. Good to do it before they reach the rebellious phase.
This is some sage advice!!!
