Query-UK born dependent not applying ILR with main applicant

Hello,
I know it isn't required for UK born dependent to apply for ilr along with main applicant as she can register for naturalization once I get my ILR. The query is in wake of so many success stories here where caseworker queries for the reason dependent is not applying at same time. Should I mention it in cover letter that reason we are not applying is as we plan to register her for naturalization on mn1 once I get my ilr?

Thank you for your advice.

Children are REGISTERED on MN1 as British.
Adults are naturalised.

Yes, you can write it in a cover letter or in the additional information page of the form but it is not necessary. Caseworkers are only checking to make sure etc, nothing more than that, it is part of their job. Not all child dependents are UK born so likely that is why they ask.

Thanks. Good point, I will just mention that dependent child is UK born and currently holds valid T1 (G) dependent visa.
