If you are concerned about your child's eating habits and fear of vomiting, it is important to pay close attention to their symptoms and monitor their hydration levels. Encouraging light and easily digestible foods like soups, broths, toast, eggs, and crackers can help alleviate any digestive discomfort. Avoiding heavy or sugary foods like red meat and undiluted fruit juices is also recommended. If your child's condition persists for more than 7 days without improvement, it may be advisable to seek medical advice from a doctor.
