أيّ طفل حسّاس جدا هو واحد من 15إلى 20 بالمائة من الأطفال الذين يولدون بنظام عصبي بإدراك كبير وبسرعة للردّ على كلّ شيء. مما يجعلهم يدركون التغييرات الغير ملحوظة بسرعة فائقة ويتصرّفون عموما بشكل واع.

قد تكون هذه الحالات الحساسة ذات صلة بالاعتداء أو العنف الجنسي أو العرقي أو الإثني ...إلخ

Discussion of topic 5 in Caring for Others: discussion of these sensitive child protection topics
needs to be handled with great care. Facilitators should emphasise the voluntary and anonymous
nature of the comments shared, and that beyond those present the comments will be treated
confidentially. If participants are reluctant to discuss a topic, facilitators should not put undue
pressure on them and should move to the next topic. It is vital that the discussion does not
inadvertently increase the risk of participants experiencing violence or abuse from others in the
community after the focus group. If any evidence of violence or abuse to children in the
community does emerge through focus group discussions, programme staff need to ensure that
this is appropriately followed up.

With respect to the provided examplary website:
Highly sensitive child طفل مفرط الحساسية أو مصاب بالحساسية
With respect to (sensitive child protection), I guess the word (sensitive) shall modify a missing head word such as (information, issues, procedures....ie sensitive child protection issues) as the collocation often occurs. In this case, I suggest المعلومات (أو أي شيء آخر) الحساسة المتعلقة بحماية الطفل
It always collocates with vulnerable children الأطفال المعرضين للأذى أو الانتهاك
