The Baby Trend Sit N Stand Double Stroller. I think what I like about this is that both kids can sit down and see out while we're trucking around. The second tier is slightly elevated so they can also see out a bit more than if they were level.
You also have the option to do an infant carrier and the regular seat. The infant carrier can be on the front or the back. I'd put them on the back so Addie could sit on the front and could see out easier.
This is how the stroller typically looks, which is actually the only option I thought the Sit N Stand came in. I kept thinking, why would anyone want the older child to be free to jump on and off as they please. And what happens when you're using this stroller at the zoo or on a long day and the older child gets tired? So I love that this stroller has so many options.
At a price point under $140 it's super affordable. You would have to purchase the infant carrier that the stroller accepts which would be an additional cost but it's about the same cost of a travel system with all those additional pieces.
I'm not sure that we're ready to pull the trigger on the purchase yet, but it's the best option I've found for what we would need. What are your thoughts? Do you have a double stroller? Did you use it often? I need advice!
