Special co-host Jamila Souffrant, founder of Journey to Launch, is back on the show, this time co-hosting and helping answer a wide range of questions from So Money listeners.

Today's questions: Is it better to make an additional principal payment on a mortgage each month or invest in an index fund? What to do when you're in your 60s with no savings or retirement? What can a professional woman in her late 20's - who wants children one day - do to prepare best for the time and money constraints of parenthood?
