My apologies for not understanding your Q fully, 
today I checked my own filled forms.
FORM 5532 Q3 Other financially dependent people
Give details of any other person who is financially dependent on you (whether they are living with you or nol) and who is not already listed in the tables above. include previous spouses or partners and any children from past relationships.
I wrote N/A under both names 1st and LAST. In your case as I can see you are still supporting 3 kids; you only write their names and D.O.B. Don't have to write yourself here. OTHERS= not you it can be previous kids, present kids, parents.
My application has apparently gone thru all checks with N/A written here so this form appeared OK to them we assume.
Thanks
