DS handles conversations about his adoption pretty well, we have rehearsed in the past what he says when people ask why he doesn't look like me or why he doesn't have a Dad. And it has been relatively fine with his peers as they have been too young to enquire too much.
For example - questions about why he looks different have been dealt with just be saying DS was born in Kazakhstan and lots of people who were born there look like DS. Works pretty well with 3/4/5 year olds.
Why don't you have a Dad - either "we don't have a Dad in our family" or "My father lives in Kazakhstan we don't see him"
Teacher has told me that it came up in his group about why he was adopted and he explained "that having a baby was very hard work and not everyone can do it so I grew in someones tummy but she was very young and I live with my mum now" - which I actually thought wasn't too bad an explanation as off the cuff ones go from a 6 year old! I'l skate over the part where he appears to think that his birth father is still living in the baby house DS was at...
Anyway one of his friends on way home to play at ours raises the adoption thing again and asks the same questions he has asked before. I think DS is losing patience with it although the questions aren't malicious they do emphasize to him that he is different and he doesn't like it being discussed publicly (very happy to talk to me about it).
So I think the time has come to teach him a way of telling people he knows (not strangers) that he doesn't want to discuss it.
I seem to remember from reading that its one of the WISE UP options - how does a 6 year old say nicely to his friends/class "I don't want to discuss it - its private" when most of them have no concept of the meaning of private at this age!
Sorry thats a bit of an essay but its bugging me.
