No, touching a baby's private parts does not break wudu (ablution).
Understanding Wudu and its Nullification
Wudu, a necessary ritual cleansing in Islam before prayer, is broken by specific actions. Crucially, the reference states: "In fact, the touching of the private parts that nullifies the ablution is the person's touching of his /her own private parts." This clarifies that unintentional contact with another person's private parts, including a baby's, does not invalidate wudu. The act of breaking wudu is limited to self-touching of one's own private parts.
Practical Implications
This means parents or caregivers can attend to a baby's needs without concern for breaking their wudu. Activities like changing diapers or cleaning a baby do not require a repeat wudu.
Conclusion
The key takeaway is that only touching one's own private parts breaks wudu.
