Anne'cdote in song

I have a song I sing for Anne that I made up:

"I love Annie, Annie Bananaie.
She's my Annie, my Annie Bananaie.
Annie, Annie, you're my girl!
I love you more than all the world!
Annie, Annie you're the one!
I love you you're so much fun!"

I sing it to her so often that she now knows all the words and sometimes to make it fun I'll stop on a word, point to her and she'll sing it. Today I stopped on the part where she would say "girl" but instead it went like this:

Me: "Annie, Annie, you're my..."
Anne: "Little person!"

Where did she get that? But it fits, even if it doesn't rhyme.
