We have this stroller and all 3 fit in there.

It is perfect for walking them. I do let them out to walk one at a time and then when they get tired, i switch to another one. We have the pink one and my hubby loves to walk with the girls in it. He sure does get a lot of attention! LOL!! We like this brand since it has the 4 wheels and is very sturdy for turning and such. When we go to places where they need to be protected, this is great as they can be in there safe and yet still see everything going on. It also has the tray at the bottom to put water bottles, and leashes. Your babies will love going out in this!!
