We just got back and this was our first experience with pin trading for my 3yo and 6yo boys. I bought 100 pins off ebay for trading (didn't care what they were since we'd be trading them), we probably needed only 60 of them them. It started slow the first day and then they really got into it. I helped them find the CM's wearing pin lanyards and then they got to look at them and pick whatever they wanted. For good manners, they had to say "May I trade please?" each time. I wore the lanyard that carried the pins, and I had a few in my bag as well. My 6yo wanted to wear his own lanyard after trading for 3 days, but my luckily my 3yo didn't care to wear one (nor did I want him to wear one). They really enjoyed it!!!
