If you had a happy childhood, what would you put it down to? what were the key elements? i think it's mostly about stability and possibly being a bit "cotton woolled" - by which i mean, protected from knowing too early about the bad things about this world, and space and time just to be innocent; not being exposed too early to pressures to look/be a certain way, or have certain toys, or whatever.
which i know sounds old fashioned...
