Does anyone else baby have stranger danger?

Because of covid i can’t help but feel like my baby has no interaction with other people besides immediate family and has the worst stranger danger! but anyone else she screams and cries when she sees someone like at the pediatrician the poor nurse and doctor! is this happening with anyone else’s baby? I am a SAHM so the attachment is real with me i’m just curious (even if she doesn’t see my MIL for a week, she cries at first till she warms up)
