A wife cannot demand payment for breastfeeding her own child, she is obligated. You call me ignorant, yet you don’t know that this verse refers to a woman who is divorced.You clearly have no clue about Islam. You're completely ignorant.
A woman can even demand payment for breastfeeding her own child:
It's in the Qur'an:
فَإِنْ أَرْضَعْنَ لَكُمْ فَآتُوهُنَّ أُجُورَهُنَّ الطلاق/6
“Then if they give suck to the children for you, give them their due payment” [al-Talaaq 65:6].
