هل تُعتبر جميع الأماكن التي يزحف عليها الطفل نجسة، وملابس الأم والطفل، وكل ما تلامسه الأم بيدها، نجسة بسبب قيء الطفل الذي يبلغ 8 أشهر؟ وهل يتنجس كل من يضع هذا الطفل في حجره إذا لوث القيء ملابس الطفل؟

It is obligatory to remove impurity, not to perform ghusl (ritual bath) for every prayer. Vomit is considered impure by the general body of scholars if it has changed from the state of food. If it has not changed, the Malikis hold that it is pure. So, if your daughter's vomit has not changed, it is pure. Even if it is considered impure by the majority, you can designate specific clothes and bedding for prayer, and wash whatever you are certain has been soiled. As for a small amount of vomit that is difficult to guard against, it is pardoned due to hardship, and this includes a baby's saliva and drool.
