I love the new Graco, the Quattro Tour 2. You can put the infant seat in front, it comes with an installation bar. You can acutally use two infant seats with it.THe older Graco, the duoglider, is hard to put the infant seat in the back. You have to avoid the push bars, almost dumping the babp on her face to get them in. The newer model, the Quattro, is so much nicer. I tried a ton of double strollers before buying this one. It turns on a dime, is pretty lightweight (seeing that its for two), and easy to push. My son loves the freedom of the front. Many have questioned whether he can get out because there is not a bar. The answer is no, the 5 point harness keeps Mr. Wiggly in place. He likes the separate juice and snack spaces. It folds really easily, although you have to watch that the cup holders don't come out.
Hope this helps
