Good night for kids
In French, faire dodo means faire dormir (literally to make sleep) or “to go night-night” in English. Thus, “Va faire dodo” is a cute way of saying “go beddy-bye”.

Common mistake: Don’t say bon nuit
Bon nuit is incorrect. This is a common mistake. Bon is the masculine form of good. However, since the word nuit is feminine (la nuit), you must say bonne nuit.
