I am thinking of buying the volo for my 4 yr. old. She is on 37 in. and 31 pounds so it sounds like this should work good for her. She is tiny. But for my 18 month old I can't decide between the triumph and the quest. I looked at both at Babies 'r us and really liked the quest, but thought the triumph wasn't bad. Maybe I am crazy for buying two strollers, but I figure it will be easier carrying them on buses. Also, I will use the strollers shopping and etc. DD 4 will be in pre-K, so I like the idea of having the single for other DD. Do you think I'm crazy?
