To use this doctor set, let your child pretend to be a doctor and start examining the dolls. They can listen to the doll's heartbeat with the stethoscope, give pretend shots with the retractable syringe, and check the ears with the otoscope. When not in use, keep all the items in the carry/storage bag. Make sure to keep small parts away from younger children to avoid choking hazards. Clean the items regularly with a damp cloth to keep them in good condition.
