Mockingbird Stoller — we love it for our twins! I linked our exact set up. For twins you need the second seat kit and two car seat adapters. I also included the accessories we bought for it. The car seats clip right into the adapters or they can sit upright in the chairs once they can sit up on their own. It can do so much for different ages and stages of twins! LTKkids LTKbaby LTKfamily
