Fund your own retirement first whether that is 401k, IRA or Roth IRA.
I wouldn't use a Roth IRA for college. You can only take out the contributions, not any of your earnings before 59 1/2.
Put the college saving money into a 529. I do that for my 3 boys. Just a small amount until I can comfortably save for retirement- all debt paid off, plus saving 20% of income for retirement. Remember they can take loans for college but you can't loans for retirement.
