Get a SRT8, 300, Charger or Jeep. All the power and room you'll need. I have a Steel Blue Magnum SRT8 (vey rare) that I bought over a C6 back in 07 because I had a newborn as well, but it was my 2nd favorite car so it was a win win for me in either case. I now have a SRT8, Nismo, SmartCar, Lincoln LS and VW CC (wife's car) which I can all use for a number of things. The SRT8 and Nismo are strictly for me cause my wife gets on my dam nerves when she's in either one of them, the SmartCar is for commuting to work and the Lincoln really serves no purpose other than just being a guest car for my sister when she's home from the service. The SRT8 can haul the entire family with a trunk full of groceries and still walk on 90% of whatever's on the highway at any given time, it's an awesome car for what it is, big, heavy, but will spin circles around my Nismo all day long and reek havoc on anything with 400 plus hp.
