It should be You as the main sponsor , I assumed you are all in joint names with your husband in bank accounts,utility bills,mortgage etc?
and please write everything in your cover letter explaining about your circumstances.
Are you collecting her in the Philippines? well, it would be nice to do so , wonderful experience to do it yourself with daughter.
Also include remittances,chat logs/communications /school/doctors letter/greeting cards/pictures together, anything that involves you and daughter send them off with your application.
By the way just an add on, when we applied for my daughters Indefinite Leave to Enter we went to the local council to get a registry form so she'll be all set to go to school on the next term(we also included that in our application documents)
Sending you my fairy dust!!
All worth it in the end.
