My recent Graham favorites:
Lots of dancing and singing
Learning to play with sand without throwing it
Learning to not be so afraid of water at the beach and pool
(although here he is obviously more interested in the rocks)
Cowboy impersonation obsession
A love of being "snuggly"
Trying to entertain friends
Asking for "two" of everything meaning "more"
examples:
I want two mommies
I want two boats
I want two pools
I want two milks
