can a mother of a four months old postpone her fast dua to breast feeding?

If the women fears any harm befalling the newborn like not receiving sufficient milk which could lead to other complications then it is permitted for that women not to keep the fast. She must however make up for the the missed fasts on other days and she does not have to give any kafaarah she just needs to fast.

and Allah Ta'ala Knows Best
