As for MCHN, they are shifty buggers at the best of times trying to leave you questioning your own choices on many subjects, if they want you vaccinate or reconsider, they'll use their Jedi mind tricks on you soon enough.
I would just like to say that is NOT true in all cases. My last 3 MCHN have been wonderful. Nothing but supportive of any choice I make (cloth nappies, extended BFing, co sleeping, BLS, not vaccinating against some things, wearing my baby) and most were not 'norm' choices. I have never once left there feeling I was doing something wrong. Helen is the one here where I have moved to, and she even said (which isn't allowed to be said by her apparently) that BLS makes much MORE sense than pureed foods, and she wishes she was allowed to tell parents the benefits of it but she isn't allowed.

I think if you walk in with a negative attitude to MCHN's you will get a negative attitude back, maybe this is why you haven't had any good experiences with them?
