| Mistake | Explanation | Correct form | |---------|-------------|--------------| | Writing (shinseiki) when you mean “newborn.” | Shinseiki means “new century.” | Use 新生児 (shinseiji). | | Adding 子 after 新世紀 → shinseiki‑ko . | The resulting phrase is nonsensical in Japanese. | Drop 子 , or use 新世紀の子 only when you really intend “children of the new era.” | | Mixing kanji and hiragana incorrectly: 新せい児 | Mixed script can be confusing. | Stick to 新生児 or fully hiragana しんせいじ for beginners. | | Using 新生児 for a toddler (over 1 year). | The term is limited to the first month. | Use 幼児 (yōji) for toddlers, 子ども (kodomo) for children. |
