First of all, congratulations on the birth of your girls! I have triplet girls that are 10 1/2 already, but I can remember the thrill of getting their first stroller when they were 6 mo. old - we could finally go for a walk! As you probably know, your choices are pretty limited. The Peg Perego and the Runabout are bothl inline. The only stroller that I know of that isn't inline or the triple wide is made by Inglesina. A friend of mine had one. It seats two side by side and the third in front, so it's narrower. The down side is I think they are ridiculously expensive, even more so then the Pegs or Runabouts. Good luck finding something that suits your needs.
