Getting ready for #2

For those of you with more than 1 child, what type of stroller do you use. I just found out I'm pregnant with #2 due in November and I'm curious about strollers. We barely use a stroller for DD. Only when we will be out for an extended time. She walks, uses a cart pr we hold her. But with a second baby, I dont think those will be options. Did you use a double stroller, two separate strollers, a baby carrier? How did you handle it, pros and cons. Just need some help and advice.
