She has to make up fasting for more than one Ramadan and delayed it without an excuse, so what is the expiation, and is the making up in order?

Question:
The woman who sent the message, Umm Anas from Jordan, says in her question: I am a woman who gave birth to a daughter five years ago, and I broke my fast every Ramadan because of the birth. After three more years, I gave birth to another daughter, and I broke my fast for the entire month of Ramadan. Before that, I had about two weeks of missed fasts to make up, so now I have two and a half months of missed fasts from previous years to make up. I do not know how to start making them up, and whether I have to pay an expiation for delaying the making up of those fasts, or if I should just fast directly. Please advise us, may Allah reward you with good.

Answer:
Making up the fasts is necessary. Allah the Exalted said: So making up the fasts is necessary for whoever is able to do so. As for the expiation, if the delay was without an excuse, meaning it was due to laziness or negligence until another Ramadan entered, then she must, in addition to making up the fasts, feed one poor person for every day she delayed. But if the delay was due to an excuse such that she was unable to make up the fasts between the two Ramadans, then she only has to make up the fasts; she does not have to pay an expiation for the excuse of the delay. As for the order, it is necessary that she fast what she owes from the first Ramadan, then fast what she owes from the Ramadan that followed it, then fast what she owes from the Ramadan that followed that, and so on. Yes.
