3rd baby.. stroller?

Rebecca • 28. Married for 6 yrs to my high school sweet heart. We have 2 daughters Ellie & Reese. We are expecting our third baby girl December 2019!

We are due with our third girl at the end of December. Our oldest will be 4 and a few months when the baby is born. I’m trying to decide if we should get a double stroller that also as the ride along board. I was thinking about the Uppababy Vista with the piggyback board. Does anyone have a 4 year old that rides on or sits in a stroller still?
