Citizenship of minor

My non british (bio dad is American)son (10) and I just received our ILR at the beginning of this month and we are now looking into citizenship. I’ve gone onto the government website, but it just absolutely confuses me to be perfectly honest and I can’t find any other information on this subject. As we got our ILR through my spouse visa, from my understanding I can apply for citizenship right away, but can my son, or does he have to wait the 12 months? I have sole custody with a clause giving me permission to obtain dual citizenship for my son, his bio father has hardly anything to do with him outside of a 5 minute video call twice a year. Would I need to seek out his permission, or will they as part of their responsibilities? He has lived here with me since we first got our visas over 5 years ago, no days out of the country

This is what it states-

"Children applying in line with parents

Children will come within this category if:

    one parent is a British citizen or about to become one through registration or naturalisation

    the other parent (if involved in the child’s life) is a British citizen or settled in the UK (“settled” usually means that the parent has indefinite leave to remain in the UK)

    the child has been resident in the UK for the last 2 years - (if the child is under the age of 2 we can accept a shorter residence period, taking into account the age of the child)

    the child is settled in the UK

    both parents give their consent to registration (unless good reasons are provided)

there is no reason to refuse on character grounds"

My reading is that your son does not have to wait. However, there is also the "both parents give their consent to registration (unless good reasons are provided)".
