Re: Those with older kids in carseats/boosters...
This is off topic I suppose and I didn't read all the posts so forgive me if it wasn't mentioned...but I was in girl scouts when i was younger and maybe you could talk to the troop leader and suggest they have one of the meetings focused around safety...car safety, bike safety, etc. In no way would it be pointing your daughter out, and it would be enlightening to the other children (and/or parents).
Food for thought? Maybe they already do that...but just thought I'd throw it out there.
