I personally believe in the power of suggestion, but it's clear that whatever that baby is saying is not baby babble, it's very distinctive from the rest of the sounds. If I heard that doll and nobody told me it was suppose to say anything I'd still be like "Wtf is that baby saying?", because it sounds so different.
