> My daughter will not get a phone at all until she's at least 16 and probably finally actually needs one.

It’s all fine and dandy, until (i) you find that they’ve actually just saved up their pocket money and gifts for the last year and a half to buy the phone (age 11 in my daughter’s case) and that all the after school and weekend activities are being arranged on phones. Seeing your kids excluded from real-world activities is tough.

In our case, a combination of talking to the kids plus Apple parental controls offered a reasonable approach.
