As I understand it, the Pearls actually have information in their book on what to do if DSS calls on you for using their methods.
To which I can only say, HUH? How can people
not know that this is wrong if they have to be given advice on how to avoid DSS? Of course I suppose that the Pearls would say that DSS is somehow satanic and are trying to keep people from following God's will.

Jesus said, "Let the children come to me." That wasn't half a sentence, with the other half being, "...so I can beat them with plumbing line."
I've only looked at info from their site once, and I cried and nearly threw up. I pray for the poor children who are subjected to this abuse. I think this is a case of "even Satan can quote scripture to suit his purposes."
My sister has a friend who used Ezzo because it was recommended by her church. She put her breastfed son on a strict three-hour feeding schedule. Long story short, he was diagnosed with failure to thrive at his four-month checkup after having only gained a couple of ounces between two and four months. My sister, who originally backed up her friend's use of Babywise, took one look at her fed-on-demand nephew and said, "Oh my God..." then added that her friend
really needed to see him. She said her friend's son was "the skinniest baby I've ever seen in my life."
