I do have experience working with ASD on some level. I am an ESE teacher, but I teach mostly learning disabled and emotionally disturbed kids. I've only had one ASD student, and he was a 1st grader that was a "runner" and escape artist, and non-verbal. So no, nothing like what I have seen in my daughter. Also, working with kids at school is much different when you see a disability in your own child.
If I could re-do the way we went about our daughter "not-knowing" about her bio-mom, I would do it differently. But the thing is, it's already done. We have to work from right here, right now. My daughter knows she HAS a birth-mom, she just thinks it is me. I do not treat her any differently from our other kids. Yes, working with a counselor to give her that knowledge is something that I know I can't keep putting off.
My ex-husband has legal custody of her. I do not have any custody. My ex and I have mutually agreed that her being with me is best for her. bio-mom will never be an issue. I do not have any kind of rights, I cannot just "adopt" her, as I am no longer even married to her father. It's a much more difficult thing, and again.. I wish I had adopted her while we were still married, but I didn't. There was not a reason I didn't. It just didn't seem necessary at the time, she is and has always been my daughter in every sense except for biologically.
She may be suffering from something that happened "in-utero" from bio-mom, or maybe she knows more than I think she does.. but I do not believe for any minute that I have CAUSED a problem. Sure I am not perfect.. but what mother is? Should I have already told her about bio-mom? probably.. but I can't re-do it.
