Babies on a Plane

People who bring babies on planes should have to share some of the burden they levy on their fellow passengers.
I propose that the babies be turned over to a surrogate who must sit directly behind the baby’s parent, with the baby on his or her lap. This way all seat bashing, hair pulling, shrieking, etc. will be directed at the appropriate person and not at my girlfriend who right now looks like she wants to kill someone.
