I have been thinking about letting my kids (7 and 5) try pin trading this visit. My question is: How do you keep your pins attached to your lanyard? The backs of the pins are not really secure as I have had them fall off before. I figure kids move around alot more than I do, so I would think they would be quicker to fall off of a child. I can hear it now... "Mom, I lost a pin!" followed by a very sad look on thier face or even possibly tears if it was their favorite! Any suggestions?? Also.... How much do the lanyards cost in the parks? And, where is the greatest selection (esp. for kids)? Or are they just everywhere? Any lanyard recommendations for a little girl and boy along w/where to find them? Thanks in advance for your help!
