Dr Yin saw my baby but refused to take a look at him. We were sent to an ENT by another specialist to have the doctor check a few things before starting other treatment to help them provide the correct treatment for my son. When Dr Yin arrived, he questioned why we were there and we explained. He then went on to say that he couldn't do anything and that my son was gaining weight fine so there would definitely not be any problems. I persisted and mentioned that we still needed him to check him out but he wouldn't. He then escorted us out of the room. It turns out that our son did have a few issues, and had Dr Yin checked, I would have hoped he would have caught it. It would have saved us months of treatment and issues for my son.
