When talking to babies, be sure to avoid using baby talk at all costs.  Baby talk is when you speak words that are not clear and concise.  For example, instead of saying, "Does my baby want a bottle?"  baby talk would sound something like this, "Me baby wan baba?"  Your baby is working very hard to make sense of the language he hears.  It is of the highest importance that you help him along by speaking properly and giving him something to work with.  When you use baby talk, it is like teaching your baby a foreign language that will be useless later in life.
