I want to learn English with my five-year-old son. I can say that I am a beginner. What are the good study plans, materials and software? thank you

Actually, it doesn't need to be that complicated. My mother helped me study together when I was in primary school, that is, she bought a repeater, put the tape in, and read while listening. She studies first and then teaches me. I have been getting 100% in primary school. It's all my mother's fault! Work hard! I believe your children will thank you for a lifetime, a competent and good mother.
