What happens to a baby if he eats a marker?

If a baby eats a marker, it can lead to potential health risks depending on the marker's ingredients. Many markers are non-toxic, but some may contain harmful substances that could cause gastrointestinal irritation or other adverse effects. It's important to monitor the baby for signs of distress, such as vomiting or difficulty breathing, and to contact a healthcare professional or poison control for guidance. Always keep art supplies out of reach to prevent such incidents.
