What is incumbent upon a woman who broke her fast in Ramadan due to a miscarriage, and was delayed in making up the missed days because of travel, then pregnancy and breastfeeding, with the approach of the next Ramadan and her giving birth during it? Is it only making up the days, or making up the days and expiation?

If someone has to make up missed days from Ramadan, and they delay making them up due to a valid excuse like pregnancy until the next Ramadan begins, then no expiation (kaffarah) is required of them; they only have to make up the missed days. It is permissible to delay making up the fasts until after the child is weaned if fasting is difficult for the nursing mother.
