So happy to read how it turned out for her and you! I was involved with my niece who the geniuses tried to claim was ODD but I just couldnt see how as her behavior suggested something different. Fast forward many years and much anguish and I stumbled upon RAD and it all made sense. Its a tough one and she is slowly getting better.
I’m glad your niece is getting better. It truly does take time.
We had some rough years - ROUGH. I used to say trying to meet her needs was like trying to fill up a swimming pool with a colander.
