What's the reason a baby girl prefers the dad instead of mom?

Obviously my parents both love me equally but as a baby and toddler, I would prefer dad over mom.

As a baby, my parents sometimes took turns pretending to leave. When mom held me, dad said "bye baby" and closed the door, I would start crying seconds later. If dad held me and mom left, no reaction.

Is there a reason for this?
