# Children & Age Groups

A **child** is a profile within a family, defined by their name and birth date. Phosra uses the birth date to compute the child's current age and map them to an **age group**, which determines the default rule configurations.

Age groups are:

| Group      | Ages  | Screen Time Default | Content Rating            |
| ---------- | ----- | ------------------- | ------------------------- |
| Toddler    | 0-2   | 30 min/day          | TV-Y only                 |
| Preschool  | 3-5   | 60 min/day          | TV-Y, G                   |
| Elementary | 6-9   | 90 min/day          | TV-Y7, PG, E              |
| Tween      | 10-12 | 120 min/day         | TV-PG, PG-13, E10+        |
| Teen       | 13-15 | 150 min/day         | TV-14, PG-13, T           |
| Older Teen | 16-17 | 180 min/day         | TV-14, R (with parent), T |

When a child's age group changes (e.g., they turn 13), you can regenerate their policy rules to match the new bracket using `POST /policies/{policyID}/generate-from-age`.
