Hi there!

Sorry it took me so long to reply. After reading about your stepdaughter, it really does sound like she has some issues. I know you might not want to interfere to the point of ticking off your husband and his ex, but you really do need to throw it at them. A child her age should be able to do normal daily functions and from what you've described, she just can't. Her parents need to realize that she should be doing so much more than what she can do.
Whether it be Autism or something else, she needs to be seen and diagnosed so she can get the proper help early on. Every child deserves that. You could always print this out to show your hubby.
My 7 year old daughter has Asperger's Syndrome. She is high functioning and can do much of the things other kids her age can do. Some thing's she can't yet do alone are bathing, going to the bathroom (I still have to wipe her), making a sandwich, small things like that. She does the humming, she rocks, sometimes it seems as if she's looking right through us. She does have some problems with her speech. She has very little friends and she just doesn't care that she doesn't. She prefers to be inside much of the time, unless we drag her outside. She eats certain foods and WILL NOT try anything new. Basically, the list goes on and on....
She has also been diagnosed with OCD and WPW (heart condition). I'll write some more tomorrow!
