Applying citizenship (adult +kids)

[contrast]

Hi all
We are planning to apply British Citizenship end of this month as we've got ILR since 21/12/2009 (5years work permit)
We are non EU family (2 adults + 2 children).
I understood that we need to use AN form for adult but not sure what form
for children. They are both born in the UK (2002 and 2006)and got birth certificates.
Do we need to use MN1 form for our children? or something...

Could you advise me what form and fee should we use or pay for our children's naturalisation please ?

Any reply would appreciated.
Many thanks
