How do you create a family on The Sims for PC

Well when you get into your neighbourhood at the bottom of the screen there should be a big blue button with 2 people in and a plus sign (+) click on that and then it should take you to the screen where you can create a family! If that is confusing on the main screen of sims 2 there should be some blocks at the bottom, I believe that is for tutorials and there I think it shows you how to create a family!
