Cars advice on which one/kind

I know this isn't a normal Glow topic but I need some advice. I need a new car. I have a Nissan Sentra now but need more room for when I have a baby. (I'm thinking ahead). I also have 2 fantastic nieces that I keep at least once a week. Should I get an suv or a car? And which ever one you pick plz tell me which car or suv you think is best. I also want something not horrible on gas. I drive 30 mins to work one way every day. Thank you in advance
