A sweet firefly that flashes slowly to the rhythm of the heart to brighten the environment around the child. Premium design and functionality to support it in pre and during sleep. Lights and sounds designed to become part of the ritual that the parent creates to put the child to sleep. The music and the soft light become useful elements to identify the moment of sleep. The preparation phase for night sleep is delicate, therefore it is important to adopt relaxing techniques for the child that reduce over-stimulation, making sleep serene and long-lasting. A ray of light in the bedroom makes the child calmer and more serene. At the same time it offers the possibility for the mother to enter and check that he is sleeping, without disturbing him. Classic songs and white noise designed to relax the child and accompany him in the phase of falling asleep. The light sequences rock him to prepare him for a peaceful and long-lasting sleep. With 2 mode buttons: melodies and light sequences. If all the illuminated parts are on, one part goes out every 5 minutes: first the body, then the wings, finally the head and with it the music. The particular lighting system that lights up the transparent parts gives greater prestige to the object and makes the little firefly even more magical. The design is designed to allow the firefly to be hung on the cradle or simply placed on the bedside table in the bedroom.
