Louisa, I think you've made a very good point about some children gaining early confidence becuase they have to.
As you say, the continuum concept can be completely turned on it's head: Babies who are cuddled and handled by a variety of people could tend become less clingy later on.
I have to admit that with both my sons, I actively encouraged other people to hold and cuddle them, as soon as we left the maternity hospital, because I wanted them to get used to loving contact from other people. I knew I had to return to work, so at some point in their future I would cease being there for them all the time. As small babies, they were happy to be held and fed by others, and their childminders and babysitters have fequently commented on their ability to settle in quickly and their fearlessness around new people. Obviously I can't say that their early treatment definitely led to their ease amongst strangers - looking at their father and his abilty to find someone interesting to talk to wherever he goes, it could well be genetic!
Of course, I wouldn't disagree with the view that much early confidence springs from having the full attention of a loving primary carer.
RE Toddler Taming: Louisa, you seem to have some definite views on this, but I'm not sure what they are. Can you elaborate on this - perhaps start another discussion? I remember someone else casting aspersions on Toddler Taming, but I'm still in the dark.
Do you mean Christopher Green's Toddler Taming? I have read it just the once, so it is not my bible. I remember mildly disagreeing with some of his suggestions, but on the whole I found it a useful book.
