If you let her pin trade and she picks the Magic Pin she won't have to wait in the line!
That sounds totally like a DS thing.
You would be amazed at what he can keep in his backpack.
In the morning I usually go over things with him, like he has a note for a teacher, or he has to remember to ask about an assignment that has a "0" or whatever. That usually helps him. He is also on medication specifically for that purpose. But he still forgets things, and then he gets flustered. He gets irritated when I remind him about things, but if I didn't remind him he wouldn't remember. DH was talking about him "outgrowing" the ADD, but I don't see that happening. He might learn to compensate for it later on in life, but it isn't going to go away.
