I have been drawing all my life and painting seriously since i was 16. I've always known my destiny was in the world of art. I just don't think I'd be happy any other way. However, I have a family to support now. I'm going for a masters degree in painting and I have a few more years left of college. I have already gotten my a.a. and taken all fine art prerequisites. I have other interests, so i wouldn't mind minoring in something our even a double major. My husband is disabled and won't be able to bring much money into our future and we have a growing toddler to support. What should i do?

Have you had exhibitions? Have people shown interest in buying your work? Have you sold work to people who you aren't friends with and aren't members of your family?
If not, it's a big risk to take. However technically good you are, if you can't make what people want then you won't make money.
Also, there isn't much studying art can teach you that you can't teach yourself. So I suggest the option - Minor in art, major in something certain to make money. That's the option with the least risk in my opinion, but at least gives you a chance to spend time on your passion :) Good luck
My profile pic is an unfinished design project for computer imaging, though only slightly representative of my work as a whole.
I've considered trying to get a certification for welding since I am already interested in metal sculpture, that way I could work in a factory if I needed it.

^^^ Perhaps, this might help?
I know a lot of people say "follow your dreams", but I doubt that they ever had money problems.
If you feel like your art courses are helping you as a painter, you should do them, but keep an open mind about what job you'll do when you graduate. You can always take a simple office job and paint in your free time.
But... it's your call. This is a huge life decision and we can't give you accurate advice on that.
if you dont mind.... why dont you even engage your husband in some kind of creative work or other work so that he doesn't feel useless and retarded but can help you in any work and feel satisfied like sitting on a counter or any home business he feels easy in... just take it as an advice... BEST OF LUCK!!!
