I was never left to cry so I cant say...but I know of babaies who werre left to cry and they have no spark iykwim...they are older now like in school and they seem so sad all the time and have no expression, and clingy and I really believe this is down to being left from 6 weeks to scream themselves to sleep..breaks my heart when I see them they are never happy and have no comfidence...which i believe is due to thinking they were never comforted.....Sorry I am rambling.

Aslo we know that it does damage the brain and can affect how we behave, but I suppose people put the behaviours down to personality...
We've all had people say 'I did CC and it never hurt my kids' and it's hard to argue that when it seems true, you can't see anything wrong with them!!
It may not be an affect you can see but I guess if you dig deep enough you will find ways it has affected people...I really hate that line..you could also say I drank alot of alcohol when I was a teenager and I am fine, well we as far as I know...but what long term damage has it done?

Sorry probably doesnt make sense?
