Which adult children blanket train their children?

I honestly can't recall any of them talking about this, and I remember a blog post where Meech bragged about beating babies. It makes me wonder if they are against blanket training or if they know how it will look if they admit they do it.

Of all of them, I'd say Josh and Anna most likely blanket train because Anna wants so badly to replicate Meech and Boob. Really not sure on the others though.
