Not sure if this will work for you but it might. Valco makes a double stroller (jogging-stroller type) to which you can attach a third seat. I think it's called the Valco Runabout Twin (The third seat is for a toddler not a newborn.) One of my friends who has 3 kids (twins and an older child) swears by it.
I think this is it:
