Sit 'n Stand for 3 Kids

NicoleWI

My kids are 5 months, 2 years, and 4 years old. We like to go for walks in the summer. Do you have a sit 'n stand that works well for 3 kids (even if it's not labelled that way)? We have an old hand-me-down one. All 3 kids will fit on it, but it's SUPER hard to push. Wondering if that's just how it is, or if a newer stroller would fit all 3 but be easier to push. 

I could wear the baby and put the other 2 in the sit 'n stand, but it's hot wearing the baby (for both of us).
