Dear Rookie Moms, What stroller will accommodate my third child?

Dear Rookie Moms,

My twin boys will be just under 2.5 when number 3 arrives, and because we walk most everywhere I am hoping to find some kind of stroller situation to accommodate everyone and I am stumped! Any suggestions would be so appreciated!

Best,
Jaime

What words of wisdom do you guys have for Jaime?
