Unfortunately no one can answer the question of what you should do except for yourself. I am 21, have changed my major twice in college, and still have no idea what to do with my life. I kinda wish someone would just assign me my plan for my career and life, that would theoretically make things easier and much less stressful, but I guess that's the exciting part, figuring things out for yourself.
It sounds like you have something stable right now and with a young kid that might be what's best for now. You may have do what you want on the side, at least until you can get a foothold in your preferred career.
Good luck, I hope you make a decision and everything works out for you
