Is washing the impurity of a child a nullifier of the ablution?

The questioner:
May Allah reward you, Honorable Shaykh. This questioner says: Is washing the impurity of a child a nullifier of the ablution?

The Shaykh:
It does not nullify the ablution, but she must wash her hand if she touched the impurity. If she touched the impurity with her hand without a barrier, she washes it. As for if she washed it through a barrier, nothing is required of her. Even if her hand became impure, her ablution remains valid and is not nullified, but she is only required to wash the impurity. Yes.

The questioner:
And she says, May Allah reward you, if I was fasting to make up a missed day and I broke my fast.

The Shaykh:
But note that if she touched the child’s private parts with her hand while in a state of ablution, her ablution is nullified, because touching the private parts directly without a barrier nullifies the ablution, whether it is the front or the back.
