Reviewer: ISAAC A BAB ARINSA  
 
Reviewer's report:  
Pg 1, line 30(9) Please replace 'prevent' with 'reduce'.  
          Line 33(10) Please adjust 'period postpartum' to read 'postpartum period'.  
Pg 4, line 55(79) Please replace 'queried' with 'asked'.  
Pg 9, line 13(164) .  Please replace the word: 'uptick' with a commonly -used term.  
Pg 11, line 52(218). Could the authors please explain why the Radio is not featured?  
Pg 13, line 55 (261). It may help the geographically -naïve reader, if the authors consid er a little 
bit of description of Indonesia in terms of spread.e.g how many islands are there, and which are 
the most populated?  
 
The authors would further enrich their paper by mentioning some reason(s) or citing a 
publication that could explain the relatively short duration of breastfeeding in Indonesia. This 
could dovetail into why the Lactational Amenorrhea Method (LAM) may not b e relevant here.  
 
I suggest that the authors consider the following papers, whose contents might add flavor to their 
manuscript:
