Cod yes, you're right. I work in a similar role (training CMs and early years educators) and I would say the same thing. I have seen the effects of poor attachment.. I just don't believe it's caused by a normal, loving family doing a bit of cc. I find some of the extrapolations in "Why Love Matters" a bit OTT and value laden though I wholeheartedly believe that love does matter and makes all the difference to what sort of person a child can become. There's the story of Dennis Potter, for example.
There's the idea that his stress responses were impacted on by his father being ill and his mother having to care for him in his infancy and a fairly shocking assumption that when he was sexually abused in later childhood he "chose" not to tell his mother because of some attachment issues. Pure conjecture, to start with.. but also, very many children who are sexually abused love and are attached to their parents and that very love and attachment is used to buy their silence
. And Dennis Potter had some terrible sadness, and depression and addiction and these are all terrible.. but he was also a great artist and I am sure had relationships and experiences that were very important to him and to those people.. because life isn't a potted summary, it is a rich tapestry, and you can be fucked up and brilliant and happy and sad and your life is still worthwhile and important and worthy.
The thing that concerns me about this sort of debate is the idea that humanity is somehow perfectible.. that if we did parenting "right" etc and could somehow regulate cortisol to the "perfect" level that the world would have no evil, or pain or stress. I know in "love matters" there's a line where they say that not everyone who loses someone or is bereaved becomes depressed and often it's those who are "prone" to doing so, but tell that to someone whose entire family is wiped out in a housefire or who loses their child. All grief is not the same, all experiences are not the same and there are genetic differences that mediate our responses as well as what happens from "attachment" (as important as it is). And some people who are prone to depression have other amazing qualities... it is not a black and white picture.
I had a terrible childhood. Mum had severe PND and other mental health issues, father is a severe alcoholic, had all sorts of traumas.. and yet I am a happy, successful person with a beautiful family and a great job and immense gratitude. True, I also have an anxiety disorder but hey, I don't blame my folks for that. They were products of their background, too. And all of it makes me who I am, makes them who they are and some of it I will no doubt pass on, whether I AP or CC or whatever. Parenting is SO profound - that Chasing Cars line always reminds me of it... "All that I am, all that I ever was is there in your perfect eyes, they're all I can see"... it's HUGE. And we will all fuck it up in one way or the other. Going the whole AP route or doing a bit of CC.. either of them as "paths" won't be enough to cocoon any of our children from our own neuroses and flaws, yet nor will our "mistakes" mean that our children are irreparably damaged because of our actions.
We are all human. Thankfully, most of us are doing our best. If you can do your best as a human, that is all you can really ask for in this life.
