One Extreme to the Next

My daughter no longer screams when strangers enter the room. She now screams when strangers leave the room. She immediately moved from one extreme to the other. Anytime, anyone she doesn't know comes, says hello and then says goodbye, it's at goodbye that Baby J. goes into a panic. Is it possible to have that much of an attachment to someone after knowing them all of 20 seconds? And where does that kind of immediate panic and fear come from?
