Well, my son spent a year in public school (1st grade), and the only "medical" issue that came up was the fluoride pills they gave out (as soon as the teacher gave me the permission form, I said, OH, no! Yes, I will sign it right away, saying he is NOT to get them!" LOL! )
I am just straightforward with my kids about it (and would be the same if they were in school, though I am sure there would be a lot more to deal with in the way of "influences"
My son knows he reacted badly to his vaccinations as a baby and we decided, after research, not to vax him anymore. DD knows we don't do that (though she was vaxed with dt last yr against my desires while in the hosp. for stitches
Goodness, like so many other things, they hear us discuss the issue often enough; My son could probably you a dissertation on the subject, lol!
I agree that it must be hard to deal with frequent messages that go against one's beliefs/practices (hey, I sent a vegan kid into public school; tell me about it
I'm glad I don't have to deal with that constantly, though I have no problem with approaching it on a conscious level; it's the unconscious programming that is imparted through such constant exposure that is difficult, imo.
As the ads say, Talk to your kids (about ANYTHING and EVERYTHING), they'll listen. Bottom line, they still value OUR opinions and experience more than that of strangers. I think far too many parents are persuaded to abdicate their parenting in this sense; to turn their kids' minds and souls over to the media and "professionals" because that is "just the way it is" and they will be seen as "overprotective" if they don't. JMO.
They'll reach their own conclusions in good time; I don't expect to determine their ultimate beliefs/values, but at least I can share mine with them and give them another viewpoint to take with them
