Is it permissible to break the fast in Ramadan for fear of a mother's milk drying up, knowing that the child is one year and four months old and eats all kinds of food?

The default is that a legally responsible person must fast, and a breastfeeding woman is not permitted to break her fast unless she fears harm to herself or her child. If she does not fear harm, for example, if her daughter eats solid food and would not be harmed by the mother's fasting, then she is not permitted to break her fast. To clarify what is required for breaking the fast in the past year, refer to Fatwa no. 92849. It is permissible to wean a child before the age of two, as explained in Fatwa no. 90906.
