How to raise a webform for minor application?

[KunalC]

I need some guidance regarding submitting an additional document through the IRCC webform for an ongoing citizenship certificate application for my baby (under 6 months old).

While raising the webform, I am asked to select one of the following options:

1. I’m the principal applicant
2. I’m a representative
3. I’m writing on behalf of the principal applicant

If I select “I’m writing on behalf of the principal applicant,” the system asks me to upload IMM 5476 or IMM 5475, which do not apply in my case, as I am the parent/legal guardian applying on behalf of a minor child, not a representative.

If I select “I’m the principal applicant,” the form then asks for details as if I myself am the applicant, even though the principal applicant is my child.

Has anyone faced a similar situation while submitting documents for a minor child? Which option worked for you without causing delays or additional document requests? Any recent experience would be greatly appreciated.
