psychology

My one question I would like to throw out there surfaced when I was reading about baby signs and how children will create signs to represent certain ideas for them. My question is for anybody who knows sign language- are any of the typical baby signs (which are very logical most times) used in sign language? If babies tend to create similar types of baby signs, one would think it could and should translate to common sign language.
