Research was done testing saliva that showed that even after the baby stopped crying the stress hormone levels were just as high as when the baby was crying. The baby gives up crying because it knows that no one is coming so there is no point wasting energy on crying.
The hormone in question is cortisol, which your body releases along with adrenaline to give you more energy for 'fight of flight' when stimulated by stress, or just through certain periods of the day like when you wake up in the morning to give you the energy to wake up and get out of bed. Without sufficient levels of cortisol ( which naturally fluctuate through out the day ) in your body you would die. We need it to function. The research that has been done on mice measured their cortisol levels under induced physical stress and it was shown to interfere with synapse firing in the brain. They have not does these studies on humans, perhaps because they were not convinced it was significant. Other studies have been done on abused children who have suffered physical trauma and sever neglect, not on children from loving, stable family homes. Many of these children were under child protection services.
There has been studies done on sleep training methods which showed children who had undergone sleep training slept better and scored highly on likability, were more alert and content during the day, cried less and the parents were less stressed than those in the control group, who were not sleep training.
Here is some useful info i'v found:
This is a very detailed answer from a doctor to the specific question of does sleep training damage babies:
http://answers.google.com/answers/threa ... 74928.htmlShe references lots of studies and explains everything very well.
In conclusion she points out that this is nothing but fear mongering pseudoscience.
I am in no way saying everyone should sleep train their babies. There are many methods and different parents will try different methods based on what they feel is right for them and their children. It's up to you as a parent to do what you feel is best for your child. But claims like these do nothing but cause unnecessary grief to parents who believe upon reading them that they've actually damaged their children, and
THAT is whats wrong.
