In this article, four personality types are being mentioned: Mellow baby, Colicky baby, Shy baby, Mr or Miss personality.
I personally believe that while a person may be born with a certain set of traits, our experiences and environment will help shape and develop our personalities. Hence, while this may serve as a guide as to how your baby will behave generally for now, he/she will very likely change over time as well. It will definitely be a humbling and interesting experience watching your baby grow and change throughout the years. :)
