What is the ruling on a woman breastfeeding her child, naturally or artificially, during prayer (obligatory or supererogatory)?

A woman breastfeeding her child, whether naturally or artificially, while praying, is an act outside the nature of prayer. If this act is prolonged and without necessity, it invalidates the prayer. Furthermore, breastfeeding often necessitates the uncovering of a woman's awrah (private parts), and covering the awrah is a condition for the validity of prayer, so uncovering it invalidates the prayer.
