since i'm making a trip to the big city for the week, im going to pick up some baby gear i've been eyeing. one thing i didn't think about ever until getting my BFP this week was a double stroller. since DS will be 16 months old when LO 2 is born, i don't really know what kind of stroller to get. Right now we have a jogging stroller that I love. I wanted to get a single lighterweight stroller while I was there but am now wondering if I should just go ahead and get something bigger and better.

any suggestions? i don't really even know where to start or best things to look for. want to avoid a true double stroller if i can get away with it.
