What is Cry-It-Out (CIO)?
(1) “If your baby is sick, then this is about as tough as controlled crying gets and you will have to be strong-minded not to scoop him into your arms to comfort him. But do try to resist as you’ll only prolong the process and his misery. Try to be efficient and calm as you change the sheet… Don’t speak to your baby, and be as quick as you can so that you don’t get his hopes up allowing him to think that he’s going to be cuddled and fed.”
