Stroller/car seat Q

Kristin • Married 2014👰🏼 miscarriage October 2014🌈baby boy December 2015💙 baby girl due July 2020💕

We still have our stroller from our son who is 4. But, we want to get a new car seat. Does the car seat have to be the same brand so it can click in the stroller?

We have a baby trend jogging stroller.

Any advice
