Does the excusable amount of impurity include a small amount of faeces found on children's clothes after using the toilet, which is difficult to track and causes hardship?

The questioner is afflicted with waswasa (obsessive whispering), and it is advised to ignore it, turn away from it, and not pay attention to it, because indulging in it leads to great evil. There is no need to ask to inspect the children's clothes, as the default is their purity. We have clarified what is excused among impurities in Fatwa (definition) No. 107496. Sheikh Al-Islam is of the view that a small amount of all impurities is excused, and this can be adopted for alleviation.
