SJ, I have done. She ignored me. I've also emailed a radio show she was on, politely, and she spouted absurd stuff about choking.
She is being disingenuous - she has an empire built on mush and to admit that weaning after six months onto table scraps, and NOT having to spend endless hours slaving over a hot blender would be to pull the rug out from under herself, financially.
I can see why she won't do it - but, as I say, she's being disingenuous and, I believe, her "advice" isn't founded on evidence-based research, it doesn't have babies' best interests at heart and I am sick of baby "experts" talking at length about things, ignorantly.
