SD20 and SD16 have a difficult relationship. A lot of it is to do with how they were forced to interact when in their mother's care.
SD20 found lots of SD16s ASD behaviour difficult and because it was ignored by their mother she felt she had to do parenting...so there was lots of resentment on SD16s part because a kid 4 years older than yourself is not the most skilled person at highlighting and supporting good behaviour.
Yesterday was SOs Birthday and it was the first time the girls have been together for more than 5 minutes since they both got their diagnosis (SD20: ADHD, SD16: ASD). It looked like it was going rapidly wrong in the first 15 minutes but we got them to both calm down and acknowledge that they might not be listening to each other well. We used a "talking stick" method to give them each space to try and explain what they had meant. Turned out that they were actually on the same page but the hurt was making communication hard.
We had a lovely family day together very ND celebration of a birthday. There is still lots of challenges ahead to help them understand each other better but it was a real success.
I'm having some time out today. My DCD has lots of overlaps with other spectrum conditions and all that energy used yesterday has worn me out!
