That is just wrong. I am no fan of "hands off" parenting but the Mom in the story has some serious issues. You cannot control your kids to that extent!
The only way to learn life experience is falling down on your face, getting up just to fall on your face again, getting up.....etc.
Sure, parents should give their kids pointers on what to do/not to do but being overbearing like this will only create weak human being used to being led hand in hand through life.
IMO person like that has snowball-in-hell's chance of surviving the real world.
