My wife was pregnant during Ramadan last year, and has since given birth. She was breastfeeding but had to stop for health reasons. She has to make up fasting for the entire month of Ramadan last year, but is finding it very difficult to fast (sometimes she is simply unable to fast) due to her employment (which is needed for the family) and whilst looking after our very young children. Should she make up the fasts at a later date, or pay the Kaffarah?

Your wife should make up the days on which she missed fasting later when circumstances are suitable. She can do that on weekends or in winter when days are short and weather is cold.
