Booboo megalomania

Now that my little one knows she's an entity by herself,  she is most keen to introduce herself to strangers, she says "imm booboo" and refers to her belongings as this is "boo's blim bla", it is "boo turn", "boo's (s)poon" etc........  

Recently when I was back home after work, the first thing she asked me was "where's boo papa?" I was stunned and this continued when we saw a grandpa feeding an infant at ikea, she asked me "where's boo dada"? now she pretty much refer's to everything as  hers! she is the center of the universe and everyone/everything belong's to her.
