I'm not a doctor, but it's important to seek medical attention for your baby in this situation. Falling off the bed can be concerning, especially if there are symptoms like vomiting, fever, and swelling on the head. These symptoms could indicate a more serious injury such as a concussion or internal bleeding. It's best to contact your pediatrician or go to the emergency room immediately for an evaluation.
In the meantime, you can try to keep your baby comfortable by offering fluids to prevent dehydration and using over-the-counter fever reducers if recommended by your healthcare provider. Avoid giving any medication without consulting with a healthcare professional first.
Remember, it's always better to err on the side of caution when it comes to your child's health. Seeking prompt medical attention will ensure that any potential injuries are properly assessed and treated accordingly.
