i agree, although since doing psych i have realised that nature is still quite important. for instance some babies are just born naturally more anxious than others (like me!), they're just like that. but the parent can definitely shape how the baby will react to the world by how the parent reacts to the baby... if that wasn't too convoluted a sentence! if the parent reinforces the anxiety then the baby will probably become more anxious.

there's all these studies about anxiety and babies. also a theory about how people develop anxiety disorders that starts with a general biological vulnerability to anxiety.
