Help form imm0008 - how many do we apply for?

[UKTo Canada 2020]

I am Canadian , our children have their Canadian citizenship , how many do we say we are applying for :
1 (as just my husband)
Or
3 (husband and children but will be including their citizenship papers)

Thanks in advance

One just your husband but still you need to put the details of your children

Can somebody please clarify this?
The number of applicants is only 1 as your kids are all Canadians already. But I don't think that you need to add your kids to this specific form. It is only for the principal applicant and any dependants (that are not already Canadian) that you want to sponsor.
Did I do this wrong now because I didn't add our kids? We sent the application out last week so maybe it will be returned now?
