Quoting Mama*AtoZ:" I babywear and i'm lame so i've never even heard of these before so i have no advice. Are they a new ... [snip!] ... than a double stroller? I can see my toddler just wanting to sit down in the stroller tbh if they were too tired to walk. " The older kid can sit or stand on the bench seat on the back
Quoting Love = Moco and Bubba:" I have a baby trend sit n stand with the two seats that the rear seat can come off for an older child. ... [snip!] ... I think it depends on your 3 year old since I know my toddler would try to climb into the actual seat instead of the bench. "
Quoting Mama*AtoZ:" is it smaller than a standard double stroller?"I Think so. The Reason i want one is because it will fit a bigger child. My Son is too tall for most standard strollers & hopefully won't feel babied in a Sit & Stand
