advantages of breastfeeding

I am doing a research paper about the knowledge regarding the advantages of breastfeeding among expecting mothers. I chose this topic because in the philippines only about 20 percent of mothers exclusively breastfeed their children because of the lack of knowledge, but i am having a hard time coming up with the questions that i hope to have answered.
some questions im thinking about are
1.what is the demographic profile of the respondents in terms of?
age
educational attainment
2. have the respondents received a consultation from their primary care provider regarding the advantages of breastfeeding?
if you guys have any tips or questions i can add i would greatly appreciate it
