Regarding family-friendliness and potential content concerns:

• Potentially upsetting themes: The series touches on complex family issues, including a traumatic birth and postnatal depression, which might be sensitive topics for children or viewers sensitive to mental health themes.
• Emotional and dramatic content: The show involves unresolved family mysteries, abandonment, and strained relationships that may include episodes of emotional distress and tension.
• Tone variation: The tone sometimes shifts from lighter to more enigmatic and somber, which might be unsettling or confusing for younger audiences or those expecting a consistently light mood.

No explicit or graphic content warnings were noted in reviews or descriptions, but the presence of mature themes such as trauma, mental health struggle, and family conflict suggests it may be better suited for older teens and adults rather than young children.
