Good choice of gift-giving or ability trainning for your kids. Listening to music during the development of your baby’s brain will increase the communication pathways of the central nervous system. In early childhood, if parents ignore the role of music, they may miss the opportunity to develop their brain potential. Harmonica is a tool for cultivating your baby’s musical literacy and ability to perceive music. At the same time, it can also exercise your baby’s lung capacity, and the skills of breathing energy and rhythm can be described as one-of-a-kind!
