Sure. In the sister and her friends play doctor story, it could be that the sister is the lead doctor. Her friends would be her assistants or other medical staff. They could be setting up a little clinic in their playroom. They might diagnose made - up illnesses like 'pretend flu' or 'imaginary broken bones'. And then they would come up with creative treatments, like using a scarf as a sling for the broken bone or giving a 'pill' which is actually a small bead.
In this sister and her friends play doctor story, they are likely to be having a great time. They may start by taking the patient's 'temperature' with a toy thermometer. Then the sister, as the doctor, would ask the patient (one of her friends) about their symptoms. They might also make little medical records on pieces of paper. It's a simple and innocent form of role - playing that helps kids develop their imagination and understanding of the medical field.
Well, usually in a'sister and her friends play doctor story', they might be imitating what they've seen in real doctor visits. Maybe they use toy medical kits to check each other's 'ailments'. For example, one could be the doctor, another the nurse, and they take turns being the patient. They might use a toy stethoscope to listen to each other's hearts or use a fake syringe to give pretend injections. It's all in good fun and a way for kids to explore the world of medicine in a playful way.
