We have 2 kids 8 & 4, they both like geocaching very much and dont mind the micros, just as long as its not all micros for the day. If we go on long hikes we dont take the kids and we usually dont trade items, but always have swag with us as well as extra logs, baggies etc if a cache needs some TLC. We also enjoy hiding some tricky micros that may not be kid friendly, but we always make sure that we hide some for the kids too!!
