baby talk

My son was telling all day yesterday that Iron Man shoots dogs, I didn't understand what he was talking about. Why would Iron man shoot dogs? Today he got the Iron Man toy with light and it's not "dogs" it's "dots".
He used to mix too words gum and gun too. In the store screaming:"I want a gun, I want a gun".
And says now, the new one:" I am loving you buy me a toy. I am loving you make me dinner. I am loving you go to park".
