Gender reveal book: read aloud at the party, answer on the last page

A gender reveal you read aloud to a room full of people, instead of one you set off or cut open. The book is still there afterwards, which is the whole difference with confetti.

The pages before the end are about the guessing. Everyone has a theory and nobody knows anything: a grandmother goes by the shape of the bump, an aunt by a dream, a small cousin simply by what he would prefer. The predictions get wilder and contradict each other.

The title, the cover and every page before the last give nothing away. No pink, no blue, no ribbon. The answer appears only on the very last page, in one short line worth saying out loud. You write that line yourself.
