Baby arguing?

Look at this two. A baby and her mom. 

They are arguing,She undertands her mom but she is not agreed with her. that's ok. Nothing surprising with that. But the problem is that the baby can't talk: However she is arguing.  How is this possible?
Well, she is not able to reproduce a word because of her madurity but she can do some tones properly and this is why she can argue. And it's so funny!!! I love her... Hope you like it, too
Kiss :)
