Reviewer's report:  
 
* This is a we ll research paper, using secondary analysis of the Ethiopian Demographic and 
Health Survey conducted in 2011  
* The analysis was appropriate, and the results and discussion were well presented  
* There are several grammatical and typographical errors in the  paper that the authors must 
correct  
o Title - is it "Ethiopian woman" or "Ethiopian women"?. Also , all over the paper 
"woman" is mostly used in place of "women"  
o On page 8 for example, line 41 to 47 was not clear as come figures or words seem 
missing  
* The limitation aspect of the paper is lumped in the same paragraph with discussion on 
association of women education and time to first birth , this should be separated
