Does touching a child's private parts invalidate ablution? Your clarification, please.

The fatwa (definition) on the website dictates that ablution is invalidated by touching the private parts absolutely, even if the touched private part belongs to a small child. This is the more cautious approach and clears one's conscience. Al-Nawawi and Ibn Qudamah support this view, as Ibn Qudamah holds that touching the private part of a human being invalidates ablution, whether it belongs to a child or an adult.
