Salary for yaya (3 kids)

Currently have our caretaker para sa kids actually i have 3kids already. 1 is 4yo 2nd is 2yo and the youngest is 1yo. I would like to ask lang sana if how much yung required salary (by law) para sa kanya anyway isa lang siya then house chores ako naman gumagawa like laba ng damit ni babies at namin bale ang focus lang talaga is sa kids so karaniwan na ginagawa is binabantayan lang mga kids, padede/ pakain, paligo, hugas ng bote ng kids and paligo. Stay out din siya. M-F ang pasok then 7am to 6pm. And if ever yung panganay ko is mag school na if ever po how much would be tje additional since ihahatid sundo yung panganay ko (walking distance lang naman) and if ever yung partner niya po yung gagawa nun. Thank you in advance and sana may makasagot talaga para maliwanagan ang aking buhay. 😂#helpandrespect
