My understanding is that the baby, equipped with only instincts / biological hardware, is hyper-aware of the raw emotional communication of their caregiver.
It's this really raw, basic emotional experience which shapes our "core" understanding of ourselves and the world we live in.
"Healthy" attachment in this early stage comes from the caregiver being able to regulate the emotions of the baby. If the baby doesn't feel connected to the caregiver - such as if when the baby cries they don't receiving loving reassurance of their safety - then they form a dysfunctional template for social attachments and poor emotional regulation ability.
If the random babysitter has consistent and parent-like loving connection with the baby then maybe you're right, but I doubt that's the case.
