High Needs Babies?

I began researching High Needs Babies after I got this idea that I had one.  Aren't ALL babies High Needs? What does that even mean anyways.  Of course she is a high needs baby she can't do ANYTHING on her own.  They described them as being babies that are tired and hungry all the time....Is that not typical? If not I guess I DO have a high needs baby.....
I think she is too mature for her age and wants to be like the crazy adult aliens that take care of her.  (Meaning me and daddy).  She fights going to sleep EVERY nap and every evening bedtime, but she is so tired and CRANKY. Again I have a high needs baby.....I guess.  She will only go down while nursing, and gets overstimulated VERY easily.....Thats a high needs baby! She DOES like to be carried all the time and played with all the time, rather than on her own....Wouldn't YOU want to hang out with the adult aliens that tend to your every waking need every time? Or, is it that high needs baby again. I dont know, I am at a loss here.  I guess I just have to come terms with the fact that I have a high needs baby....Or that I have a baby.
