**Key Considerations:**

* **Target Audience:** Who is the audience for your WordPress blog? Are they parents primarily? What is the tone of your overall blog?
* **Post Content:** What kind of content are you tagging? Is it about practical advice, emotional sharing, or a mix of both?
* **SEO:** Use relevant keywords. While “親子共浴” is already in the title, you could consider adding extra keywords in the description if relevant (e.g., “兒童洗澡”, “親子關係”, “沐浴安全”).
