Is a child's vomit impure, necessitating the purification of everything it touches, or is it pure because it is something that is widespread and difficult to guard against?

Scholars differ regarding the impurity of vomit. The majority of scholars hold it to be impure, while Al-Shawkani and some contemporary scholars, such as Sheikh Al-Uthaymeen, consider it pure. A small amount of vomit is excused by a group of scholars.
