This is for my doctoral thesis and I would like to look at the factors that increase motherly guilt and dissatisfaction or reduce confidence in their abilities and how these affect their mental health.
Have you considered research that has been conducted using the approach fo Institutional Ethnography? May I suggest the work of Lisa Watt as a place to enter into this type of critical social research? Good luck with your doctoral thesis! https://www.wmich.edu/hhs/newsletters_journals/jssw_institutional/individual_subscribers/42.2.Watt.pdf
