controlled crying study

Interesting that they are validating it using cortisol. As far as I am aware young mammals do not have adrenal glands well enough developed to use cortisol as a stress indicator. Which is why we don't use it in animals to analyse stress response of young animals eg lambs to stresses such as transportation. So it would be interesting to see their methodology as to when they start taking initial saliva samples to measure an increase. Also I hope they aren't just looking at cortisol but also long term effects such as disconnection of maternal bonds etc.
