Dropbox and visa interview appointment for family with kid

[chnrbk]

I am a father of a 12-year-old kid. I have a question about scheduling the VISA appointment for the three of us.

My kid and wife have not traveled to India for the last 6 years.  I am eligible for dropbox because my last visa got expired this year only.

As per the Visa Dropbox checklist, I am eligible for dropbox, I think Kid is too because he is under the age of 14 years, but my wife is not eligible.

I would like to get your feedback on how to schedule the visa interview for all of us in this case.

A. Do I need to create CGI profiles for each of them separately?

B. I can include Kid as a dependent in my profile and schedule dropbox for both of us?

C. Create a profile for the wife separately and schedule for OFC and Consular interview?

D. Or is it possible to include all of them in one profile but can schedule the visa interview/dropbox separately?

Or is there any requirement that the primary(me) applicant must get the visa first?

Appreciate your response. Thank you
