Does breastfeeding a child invalidate ablution (wudhu)?

Summary

Breastfeeding a child is not among the things that invalidate wudhu. The fatwa lists four invalidators: anything exiting the front or rear passage, loss of consciousness through sleep unless sitting firmly on the buttocks, skin contact between an adult man and an unrelated adult woman without a barrier, and touching the private parts of a human with the palm or inner fingers. Anything exiting from other than the two private passages, if not impure, is not considered a hadath by consensus of the scholars.
