I already have the single stroller. WOuld I need both the car seat adapter and the cocoon? Could I get away with just using the cocoon that way I can seat both the baby and DS if he gets tired. I usually just babywear anyway, so I don't normally carry around the infant seat...but I don't know if that will change once I have 2.
Re: Another Phil & Ted's question
We aren't getting the carseat adapter. You can't use it and the second seat anyway. Not sure what the cocoon is so obviously we aren't getting that either. We plan to babywear or use the bassinet.

You didn't mention getting the jump seat, which I think you will need (at least at some point).
And even though it's not recommended, you can use the car seat with the 2nd seat in the back - as long as your toddler isn't super heavy (maintaining the weight balance of the stroller with the car seat/newborn). I didn't get the adapter, but my Graco car seat fits on the stroller just using the bar that comes with the stroller.
