Can the mother ask the father for payment in return for breastfeeding her children from him?

 

known that if
you study the situation of people at the time of the Messenger (blessings
and peace of Allah be upon him) and until the present day, you will not find
any woman who asked her husband for payment for breastfeeding a child. And
this is the correct opinion. End quote. 

Al-Sharh al-Mumti’, 13/515, 516 

And Allah knows best.
