Baby, currently 12 lbs, does not like the car seat or bassinet (Uppababy) for any extended period of time on the stroller.
Bought the &Roll since the Vista 2 can’t handle off road terrain very well and I wanted to be able to jog with baby and the pup. Lucky the Switchback reclines and is with the infant insert baby is fully supported. We are able to get in 1 hr walks without any fussiness. Highly recommended this seat.
