What career should I look into?

Hey all! 31F looking to invest in a career with a little more substance and hopefully a better paycheck.

I currently make roughly $46k before taxes working as an accounting clerk for a car dealership. I have a 401k and I pay for my own health insurance. I just had a baby 2 months ago, and live with my husband and baby, our house and cars are paid off.

What interests me are nursing, ultrasound tech, dental hygienist, pretty much medical field related. It doesn’t necessarily need to be but I know some of these (if not all) need pretty dedicated time, which I’m not opposed to but would need some of it to be online as I have a new baby and will be returning to work.

Anyone have any suggestions?
