Parents pay more and more attention to their children's early education. They don't want their babies to start at the starting line. Picture books, children's songs, counting and even piano and dance all let the baby learn early. Of course, in order to let the baby fall behind others in mathematics after primary school, the addition table within 10 should also be memorized.
