Also, let's allow children to play with their own things at certain times.  I get a negative physical reaction when I hear babies should go to school where they will learn to socialize and share.  Poor little things!  Some of them find being part of a group quite intimidating and taxing.  Others may love it, but the expectations are the same for both types of youngsters.

Let's talk about sharing.  It seems way over rated when applied to the very young.  Kids need to identify with  their own things.  It brings comfort and sense of self.  why not a container for each child having only his or her things.  Hands off to all others unless invited to share by the owner.  After all, teachers in those same rooms are heard to ask one another, "Have you seen my pen?"  Why aren't there just our pens?  Adults take ownership of things for granted.  Why not kids?
