Dropbox eligibility check for my son

Our visas(H1 and H4) are expired and planning to go for stamping. Now with the ongoing issues with USVisa Scheduling site, I am not able to take appointment together. They are asking to create separate profile for my wife and son; and book appointment. I know if I take appointment for all three of us then I can go for dropbox. But if I create separate profile for my son who is less than 14 years, will he be eligible for dropbox?

The dropbox eligibility is tested separately for each person irrespective of whether they have different online website profile or not.

So, your child should qualify for Dropbox irrespective of whether you qualify or not.
