I never thought of kids being worried about their toys eco- I think we have always tried to have the attitude "easy come, easy go" with belongings. I think that if the questions were really getting that indepth I would go with short yes man answers, like - everything is replaceable- everything. The likelihood of ever needing to come through on that is so low, and to be honest just about everything is ( for a price).

I haven't had to deal with the anxiety though...
