My children have been teaching early in small steps at home. The main reason for the beginning is that I like small-step courses in addition to high-quality companionship. I feel that the whole teaching process is very interesting, and some Tan Ya and children's songs interspersed in the middle are also very nice. My family Nini likes it. Listen to it again every time after class. As for the Qiao Hu early education you asked, I haven't used it yet.
