Stroller for infant and 1.5yr old?

Kaitlin

I am due with baby #2 in November. We have a little boy who will be 16 months when his sibling arrives. I’m not sure what stroller to get! We have the Chicco Keyfit 30 car seat currently so I’d need something that is adaptable for that. What are the best double / tandem strollers? Not looking for a sit and stand - definitely need two seats. Thanks!
