Adding a prediction
From a child's vault, open Future predictions. Each family member can add up to three short predictions to the year's open round, in a few words: what they'll grow up to do, what they'll be like, anything you like to imagine. You can edit or remove your own prediction while the round is still open.

When predictions seal
Each year's round seals on the child's birthday. Once it seals, nobody can add, change, or remove a prediction for that year, and a new round opens for the next year.
When they open
Every sealed year stays private until the child turns 18. At that point, the whole Book of Predictions opens, and the child (or the adult they've become) can read everything the family guessed about them, year by year.
