Is getting a Bachelors degree in Education a good idea?

I love children and would love to teach. I also love being able to provide for my family. I am a single mom of one (son age 11). I am going back to school in the fall to pursue a Bachelors degree and I am stuck deciding because I also like computers but I love helping children. So it's either a Bachelors in Education or Computer Science. People are saying teachers get laid off a lot. How far can I make it with a degree in Education? What kind of jobs would I be able to get? And financially would I be able to live and provide for my family while saving for retirement as well? I currently live in Maryland-Baltimore County
