The Essential is a sleep trainer with projections that helps children know if it's still time to sleep or if it's time to get up. If the rabbit is lighted up in the sleeping position, the child knows that he still has to sleep. At the time set by the parents, the rabbit goes into an awake position. The child knows he can get up! We can even accompany the day / night change by a projection of a moon / sun. There are 3 choices of screen light intensity! Parents can schedule the morning wake-up time and nap time at a time of their choosing. Changing from lying to awake position can be done without alarm (silent mode) or with alarm (birdsong).
