Madeline Levine explains in the NYT on Saturday:
A loving parent is warm, willing to set limits and unwilling to breach a child’s psychological boundaries by invoking shame or guilt. Parents must acknowledge their own anxiety. Your job is to know your child well enough to make a good call about whether he can manage a particular situation. Will you stay up worrying? Probably, but the child’s job is to grow, yours is to control your anxiety so it doesn’t get in the way of his reasonable moves toward autonomy.
The whole piece is worth a read. Go.
