The seventh guide in the Little Bodies, Big World series for parents of children aged 1-5. Consent education doesn't begin with a teenager in a sex ed class. It begins in the living room, with a tickle game, when a child says stop and we decide what to do next. This guide explains why laughter is not a yes, what we accidentally teach when we keep going, and how one family rule — when someone says stop, we stop, every time, immediately — builds something children carry into every relationship they will ever have. Covers the research, age-by-age scripts from 1 to 5, the tickle practice game, what to say when other adults don't follow the rule, and the profound long-term impact of the smallest possible change.
