You know, something just occurred to me about this thread. I think that what is being confused here is trust and attachment. When people are saying that babies need to trust what I think they are really referring to is that babies need to attach. We are biologically driven to attach as a baby so that we can be cared for. But that attachment might not be healthy. We can be attached without being trusting. Erikson's stage is trust vs. mistrust, this means that mistrust can develop instead of trust.
