A lot of people are going to read your post and encourage you to stay (I see nothing wrong with that!) However, I want to be a positive voice in the other direction and let you know that there is ABSOLUTELY nothing wrong with you changing your major/mind.
You can work with babies and not be a nurse. You can get a degree in social work, psych, etc (Associates or Bachelors at first) and work for agencies that help kids, infants, and families. You can also work with a lactation consultant (or become one since you DO NOT have to be a nurse)! No bad smells, gross sights, no memorizing the human body, no cleaning up, gathering, or learning about bodily fluids (except in the case of becoming a lactation consultant). You only need to learn a lot of interesting theory in school and application, which you will apply in the real world through work experience.
Social Services, like Nursing, is very rewarding. I never once asked myself if I had made a difference at the end of the day. In fact, I would continue to be doing it if I had not been bitten by the nursing bug (I worked with nurses and picked up much of what they taught me quickly because I have always been good and interested in science and great with leadership).
By the way, if you change your mind when you are older (no guarantee you will since I know people who make 30 year careers out of social services because he/she loves it too much) nursing will still be around. Therefore, right now there is no need to fight against changing your major. Again, there is nothing wrong with you; changing your major might be in your best interest! GL. :spin:
