My daughter is 5.5 years old and is an only child.
She has a friend named "Kirksy" that is a girl and plays with her when her friend isn't over (I am a nanny 3 days a week).
I don't encourage or discourage her talking about Kirksy, but I will listen to her stories about her and what they do.
It has just been in the past few weeks that "Kirksy" has shown up.
She has a neuro disorder called "Complex Motor Stereotypy" and is seen twice a month by her pediatric neurologist who also happens to be a chiropractor. Is this something I need to bring to the attention of her neurologist?
