You might dig around in research regarding premature babies. It is a highly desired topic of study-so tends to get decent funding-thus resulting in more studies and more data.
One of the key details that has been studied is the need of babies for physical touch and what it does in terms of benefits and how-which-very well could lead to finding more info on oxytocin in that circumstance-which doesn't cross directly to adults-but could lead to some interesting theories and ideas.
Also-I wanted to say-I skipped your thread for several days because I thought it was spam. So you might consider re-wording your title so that it is a little more obvious that it's not spam.
Great topic by the way!
