Picking a favorite child is an insane thing for a parent to do. While you can secretly have a favorite child—whether it’s the one you get along with, the easy kid, or just the most mellow child of the bunch—it’s positively unethical and cruel to make that favoritism known in any way. While it’s human nature to rank things, it’s pretty evil and just downright bad parenting to rank your kids against each other—especially when your «least favorite» kid is the adopted one.
