Objective: Parent–Child Bond It’s bedtime for the four little marmosets! With mom or dad, help them fall asleep by performing calm and affectionate actions such as stroking their hair or singing a soft lullaby. But be careful not to wake them up, or you’ll have to start all over again! Time for Bed, Marmosets! is designed to foster a positive parent–child relationship through gentle and enjoyable shared experiences. It allows children aged 3 to 7 to spend special one-on-one time with a parent by performing various caring and affectionate gestures that can also be integrated into daily routines and bedtime rituals, such as singing lullabies, stroking hair, and giving hand and back massages.
