But i thought you are the applicant (not your baby?)
Yes, and also members of my family, including the new born, since i applied as a married lady with child and with an additional new baby who is my dependant (applicant), i downloaded a copy of the form for him, filled, signed and submitted for him.
I'm sure you and you hubby filled your forms and submitted to KCC, also your new baby will need a filled form to also submit to KCC before you become current. On your babys form, he is the applicant, like they'd need his/her datas and also signature, but since he can't sign as a minor, you can sign on his/her behalf.
I hope you understand.
