PMID 41225754

WHAT IT FOUND

Experienced multiple-birth family professionals described leadership, submissiveness, and speaking roles in twins: one twin took space, decided, or spoke for both, while the other waited, followed, or became quieter.

Key findings

01Of 72 respondents, about half answered the open questions: leadership n = 34, submissiveness n = 37, and speaking role n = 34.

02Leadership was described as one twin taking space, being dominant or demanding, deciding activities, and speaking for both.

03Submissiveness was described as giving space, watching from the sidelines, being controlled, and giving up the voice, and was linked to slower speech development.

What it does not show

The participants were health professionals, not parents, children, or families, so the findings are perceptions rather than direct patient or family experiences. Fewer than half answered the open questions, and some respondents said they did not know or had not heard of the issue. The study used a one-time questionnaire rather than interviews or direct child assessments. It did not test whether the described roles are fixed, how they change over time, or whether any advice changes outcomes.

Declared interests

The authors declare no conflicts of interest.

The easy way to misread this

Do not read these themes as proof that every twin pair has a leader and follower or that any advice changes outcomes. They come from health professionals' perceptions, and fewer than half answered the open questions.
