Forgotten Bits

Great things Jack can do that I've forgotten to write down:
Stack things
Drink from a straw
Dance on command
Go down one step all by himself
Hold a spoon and put it in his mouth.
Put the lid on a plastic container and take it back off.
Look between his legs and giggle.
Shove food into his mouth until there is no room for any more and it starts coming back out again. (Is this a talent?)
