Share and share alike

Looking after Kimberley today, she wants to be picked up while I'm at the laptop.  She leans forward and splays her hands all over the keyboard.  Then, when she is done, she picks up the hand of mine that isn't holding her and drops it on the keyboard, as if "it's your turn now, Daddy."  A few minutes later this whole process is repeated.  Recently, she is apt to eat a bit of food and then try to share the rest with whoever is feeding her.  And all this is completely untaught, at least directly.  Maybe she's picked it up from us as parents and her granny, maybe it's innate, but either way it's adorable.
