Review

Reviewer's report:
I thank the authors for preparing a manuscript on this interesting and relevant topic. Here are some
suggestions to strengthen the paper.
1. Where applicable, authors should demonstrate some consistency in the use of numerals or spelled-out
numbers. For example, p.2 lines 37 and 42.
2. P.4 line 20 - An employment status can change, but it cannot rise. The authors should consider
rephrasing this. 
3. The manuscript would benefit from a more concerted proofreading, as illustrated below. 
For example, the indefinite article 'a' is missing in some areas.
p.4 line 37 - Although (a) declining fertility rate 
p.5 line 11 - when (a) woman
p.5 line 13 - literature as (a) very
Other examples of errors
p.5 line 39 - 40 - (c) the study design was observational or intervention(al).
the authors also replaced 'at' with 'in' in some instances (for example p.10 lines 26 and 29)
4. The article used as the source for the conceptualization of maternal adaptation did not actually provide
a conceptualization. Authors should consider using a more relevant resource. 
5. P.9 line 28 the authors' use of the term 'psychological distress depression' is confusing, given that
psychological distress is distinct from depression
6. I find the explanatory indicator for cognitive adaptation to be too limited. Since this is not a qualitative
study, using only the parents' willingness to have another child is not enough of a measure. There could be
a plethora of underlying reasons for this decision. 
7. The results section merely presented a list of factors that affect maternal adaptation, without some
explanations to demonstrate how the linkage occur between the factors and resulting adaptation. 
8. Please update list of abbreviations to include PICOS
