Is a woman required to make up for missed Ramadan fasts due to pregnancy or breastfeeding, and what is the evidence for that?

Pregnant and breastfeeding women must make up the fasts they missed in Ramadan, based on the Almighty’s saying: "But whoever among you is ill or on a journey [during them] - then [he is to make up] an equal number of other days." Imam Malik considered this a type of illness, especially when there is fear for the child.
