The shared-custody problem

Two households. Two sets of devices, or sometimes one device that travels. Kids navigate different rules at each — and sometimes learn to play one parent against the other.

Core principles

  • Align on the non-negotiables — no devices in bedrooms at night, no adult accounts before age 13, no sexting, no paying scams. Everything else can differ.
  • Be explicit that rules will vary. Kids adapt to different contexts (they already do at school, at grandma’s). Don’t pretend otherwise.
  • Don’t weaponize tech. Loosening rules to be “fun parent” harms the kid and relationships.
  • One source of truth for accounts. One parent holds the Apple ID / Google account credentials and manages settings. If trust is difficult, a family lawyer can mediate.

What to coordinate

  1. App-store age rating (match between homes).
  2. Purchase approval (who gets the Ask to Buy notification? Can it CC the other parent?).
  3. Screen time limits — agree on daily/weekly total, even if split.
  4. Location sharing with both parents.
  5. Monitoring-tool subscription — pay and manage jointly, or alternate by year.
  6. Social-media account passwords — shared in a password manager both parents access.

When there’s conflict

If one parent refuses to participate in controls, you can’t force the issue across households. Focus on:

  • Maximum protection in your own household.
  • Network-level filtering (router/DNS) — travels with the device on your WiFi.
  • Monitoring tools that follow the device (Bark, Qustodio, Canopy).
  • Keeping the conversation open with your kid — no shame about what happens at the other house.

The grandparents / sitter problem

Extended-family caregivers often give unfiltered devices. A one-pager of your rules in the kitchen helps. So does the family DNS at grandma’s house — many routers can be set by guests.
