(English) Lee Jina, who used to be a working mom, observed how her daughter Seoyeon's linguistic abilities weren't developing as readily as she had hoped, and that’s when she realized that a mother's voice plays an important role in teaching languages to her children. Her next step was to start learning various languages in the hopes of applying the same methods to instill foreign language skills in her daughter’s daily life. After six years of trials, errors, and grueling efforts, the author and her daughter now speak five languages (Korean, English, Chinese, Spanish, and Japanese).
