I have taken a split and stand for all 3 of my kids (older 2 were lightweights) and 2 strollers when I took the 2 kids (and the one growing in the tummy).
I didn’t mind 2. Dh and I both got to push, actually my parents were with us and my dad liked to push as well! We had a light weight graco that reclined (we aren’t stroller nappers), had a big canopy, large basket under it, a small tray and cup holders. We lived that thing! And we took the Jeep umbrella one which was great as well!
The sit and stand with all 3 kids on got heavy but it was easy to maneuver since it was narrow and wasn’t that long. But the front has the 25-30 pound 2 1/2 year old and the back had the 30 pound 5 year old and the 40 pound 7 year old (she got tired and fought her brother to sit so they shared the seat and were happy). But it was heavy going up the little hills, lol!
