I'd love to show this video to all the people who have said to me that dd won't be affected by her adoption/ won't remember her time in her birth country etc. I'm not naive enough to think there won't be issues later on.
Cc is entirely 'occasional innattention' for a specific reason, and doesn't affect the other 12 hours a day of attention, so the cortisol release is by no means constant. And cortisol release would slow down in cases of neglect - it would be situation normal, so not a situation triggering cortisol release, but would have developmental implications for other reasons (lack of interaction etc)
So, two completely different things.
I have two kids with sn - one with developmental delays and brain damage, and the other with attention/ social issues which we are fairly sure came from extended cortisol bathing of the developing brain in utero.
Cortisol is fascinating stuff, but most of the claims to do with cc etc, and everyday stresses during pg are entirely fallacious. We have a great early brain development team a couple of hours away who run weekend workshops. V interesting.
