No doubt she wouldn't think of all that on her own but I also have no doubt these victims are mortified by their abuse becoming public.
I recall a commenter with a small baby, on a site about blanket training, saying, "I can't wait to start this. I'll be able to watch the game this Sunday in peace!"
This post omitted quite a bit from how it works. First of all, the Duggars have been quite smart not to include the more unsavory parts of child training from their statements. But just google To Train Up a Child by the Pearls, which the Duggars follow and have promoted for years, and you'll see.
Second, for some reason the main part of blanket training Duggar style per their books was left out of your post. Understand that those of us who've researched the Duggars are not making allegations without being able to support them.
Importantly, the benign quote you posted is from their second book. This was after they received backlash from describing blanket training in their first book, which included placing a baby on a blanket, with toys, and then "tapping" the edges of the blanket with a spoon or something. When the baby crawls off the blanket, Michelle would "correct" the baby and place it back on the blanket.
Michelle describes leaving the baby and hiding around the corner, peeking. When the baby climbs off the blanket, she ran quickly back there and "corrected" the baby. She describes training her twin boys. She describes one baby witnessing the other being corrected and thus not moving off the blanket himself because he learned from his twin's "correction".
That's how it actually works.
