Dear Jan,
Every child is so different, so unique...here is what I did with my god daughter, very troubled after spending early years with a toxic mom...
At the age of nine she was unable to bear any negative feedback at all, or even neutral. So I would say, right out of the blue; "You have been doing SO WELL, you are growing up SO beautifully - you have been doing (whatever tasks) so nicely, that we have simply NO CHOICE but to go out and do (a fun, grown-up adventure) that I knew she would like.
You should have seen her! She would then literally search out ways to do more wonderful things, taking on whatever responsibilities she could find... she just did it herself, as she was ready...
