Yeah but now they are having full conversations with them both.
Brian I know always had bit speaking parts but generally it wasn't really something they used in the front of the show...more like running gags.
Stewie they never acknowledged maybe because he was doing baby speak to their ears...now it is acknowledged a bit more, almost to the point of conversational content.
