Using this Doc McStuffins toy hospital set is super easy. First, open the tough plastic case with glittery details. Take out the talking stethoscope and press the buttons to hear 15 sounds and character phrases from the show. Use the otoscope to check Lambie's ears, and the syringe and plastic plasters for pretend treatments. When you're done playing, put all the items back in the case. Remember, this set is for kids aged 3 years and above. Keep it away from children under 36 months because of the small parts. To maintain the set, keep it clean by wiping it with a soft, dry cloth. If the stethoscope stops working, replace the 3x AG13 batteries that come with the set.
