I have never heard of either. We use Kangos Pediatrics in way far North Austin, and we live in way far South Austin, and they have been worth the drive. Ours are not vaccinated, and we've never received any lip, just signed the paper on vaccine dates (I think I've only done that once or twice, so it's not every time) "are you getting any shots today?" "No" "Ok, sign this" and that's pretty much the entire conversation.
They are also WAY open to echinacea, (we used it for ear infections), not quick to suggest tubes for kids at all I think he said maybe 2 kids a year he suggests get them. Also, very savy on homemade baby food, and even when my LO was 6 mon old, I thought of making my own formula (not BFing, long story) and they said that would be fine, or just use a milk alternative than formula. We used Hemp and they were glad they got all the info on it from me. Also they know a great Pediatric nutritionist here, and they refer out all the time if something is over their head.
