Thank you for this platform to resolve our confusions.

I'm working on factors affecting breastfeeding duration in Pakistan. I want to apply Cox regression model. For this purpose I need Status variable (including censored, uncensored observations) but I found in PDHS 2012-13 PKKR file that months of breastfeeding are only given for women who are still breastfeeding. So, these observations are right censored but to run Cox regression model I also need exact survival time (exact months of breastfeeding) but in data file women who are not currently breastfeeding their status (yes, no) is given rather than months. How can I obtain/compute exact breastfeeding duration for those who have stopped breast feeding. In literature it is found that some authors have taken age at weaning for this purpose. I can't find this variable in the data set. So, kindly share with me that how this variable can be computed.
Thank you.
