I agree... be prepared for that client to leave. Sometimes when a parent gets an idea in their head that "their precious" is being bullied or is upset, it will never change no matter what you say. I had the same type of thing happen with a 4yr old girl and she old her mom that my DS hit her and thats why she didnt want to come. Well me DS was not home that day (he went to track almost everyday after school)... but no matter how many times I told her that she would still comment on "that time DS hit her DD". It only stopped when I terminated them.
