I'm a Growing

I used to talk in goos and gagas,
but now I talk in ain't nuthin's and un-ahs.
I used to like dinosaurs,
But now I like books and nature.
I used to be 3ft 4,
But now I am 5ft 1.
I used to need a kiss on my boo-boos,
But now I just say a few unpleasant words.
I used to hate artichoke,
But now I love it with cheese sauce.
I used to have to check my bed for monsters,
But now I just have to check the closet.
I used to be a kitten,
But now I have been reincarnated as a person-thing.
