Hey T.,
I have the Peg Perego Aria. It is a side by side double and it is extremely light - this is especially helpful when they get bigger and heavier. My twins were 17 mo old when my son was born. I usually put the baby in a Bjorn or Sling-type carrier - and actually didn't use the stroller much, the twins held my hands and walked. When the baby got to be 6mo or so, he went in an umbrella stroller. My girls are crazy and active, but they learned very quickly how to stay with me, I gave them each a special job as we walked, and that helped. When I did use the double stroller, I often put two in the stroller and the other held on to the push bar and stood on the under carrier. This worked great and I didn't need any additional pieces to keep track of. We just went to the zoo, now my twins are 4 and my son is 3, I took the stroller along and they all sat in it, two in the seats and one in between on the bar that separates the two seats. They loved it and everyone had a ride.
