What should you do while a child is vomiting?

Supporting a child over a bowl while they are vomiting is the most appropriate action to take in this situation. This approach ensures the child is in a safe position to vomit while minimizing the mess and providing them with comfort. By supporting their upper body, you help them maintain a comfortable position that may alleviate some distress; it also allows you to keep a close eye on them for any signs of further complications.

Letting the child lie down could lead to choking if they vomit while lying flat, as their airway may not be protected. Sending the child outside is not advisable as it could expose them to the elements and isn't a safe area for managing vomiting. Although offering water might seem like a comforting gesture, it is not recommended until the vomiting has subsided, as it could further upset the stomach or lead to choking. Therefore, supporting the child appropriately is the best course of action during this uncomfortable and potentially dangerous situation.
