I am a social worker and parent in Australia concerned about the western practice of a method called 'controlled crying' that is used on infants to get them to sleep. This blog talks about the use of this method and other parenting methods. Search all the information on this site to be better informed about the practice of controlled crying.

SA study to settle battle of cry babies debate
THE long-term health impact of controlled crying on babies will finally be determined by a world-first study in South Australia.,22606,24305993-5006301,00.html

The wording of this article seems to indicate a bias on the part of the researchers, which - if true - would then indicate that the researchers need to seriously consider and document that they are indeed already biased, if they are to conduct any decent credible research.

But if there is any possible risk to the babies, then how is the research being permitted through the ethics committee?

Many professionals and mothers have asked this question and the resulting petition can be signed at this link;

We the undersigned strongly object to the conditions of the study on Infant Sleep Disturbance, which is being conducted by Kate Jackson at Flinders University.

We are concerned that the children involved in the study will be subjected to ‘sleep training’, otherwise known as controlled crying, cry it out or controlled comforting. This aspect of the study is inconsistent with Flinders University Ethics policy [1], which requires researchers to protect the rights of their experimental subjects.

The Australian Association for Infant Mental Health [2] does not support the practice of controlled crying stating that the technique “is not consistent with what infants need for their optimal emotional and psychological health, and may have unintended negative consequences”. If there is ANY concern that controlled crying could be harmful to infants, then the rights of the child are not being protected and the study should cease immediately.

We are also concerned with comments that Kate Jackson has made to the media which display bias unfit for someone conducting a scientific study, “Conflicting advice about controlled crying meant some parents were being scared off the technique” [3] .

As informed individuals we question the theoretical foundations of this study, in particular, the definition of 'sleep problems' [4]. There is evidence to support that it is completely natural for infants to wake often during the night throughout their first year and beyond [5,6]. This is NOT a 'sleep problem'.

Controlled crying and other similar regimes may indeed work (although one Australian baby magazine survey found that only 8% of mothers who used controlled crying said that it worked for more than a week [7]) to produce a self-soothing, solitary sleeping infant. However, the trade-off could be an anxious, clingy or hyper-vigilant child or even worse, a child whose trust is broken. Unfortunately, we can't measure attributes such as trust and empathy which are the basic skills for forming all relationships[7].

We suggest that a study into the true causes of parent fatigue would benefit families much more than this proposed study.
