No. The Australian Infant Mental Health Association does not recommend the use of controlled crying or cry it out (CIO) as a sleep strategy. They believe it could lead to emotional and mental health issues later in life. This does not mean your baby will not cry in protest at the changes to their existing routine when you implement your new one however, I want you to choose a method that feels comfortable for you and your baby or toddler and be as gentle as possible. I don’t want to cause distress for your baby/toddler or yourself.
