Must a breastfeeding woman make up the days she missed in the previous Ramadan before the arrival of the coming Ramadan, or is it permissible for her to delay due to her child's weak condition and need for breastfeeding?

If a breastfeeding mother fears that her milk supply will decrease, thereby harming her child, if she fasts, there is no blame upon her for delaying the make-up of Ramadan until after the next Ramadan. She is only required to make up the days without expiation, because she is considered to be in the same category as a sick person.
