Making sense of Benjaminese

Benjamin has started calling his teddy bears "baby." I couldn't figure out where he got that from and figured he was just not quite saying "bear" right. Then today while I was in the kitchen he was playing with one of his bears that has a button you press for it to talk. When you press the button, it says "I'm a good hugger, yeah baby." As soon as Benjamin heard it say "baby" he started saying it too. Mystery solved. His bear is confusing him. :)
