How do I add another child?

In the app, add a child with their first name, their age, and the language spoken at home. The age decides which activities appear and how hard they are; the language decides which one Jubbo explains things in.

Several children can play the same round. When they do, the activity follows the youngest in the room — nobody is asked the twelve-year-old version of something because an older sibling is there — and each child gets their own words, so nobody is asked the one their sibling has just had.

A friend who is visiting can be added for a session and remembered for next time, with just a first name and an age.

A grown-up can join a round too, under whatever the children call them. Grown-ups play but are never scored.
