We got the bob double, and kinda regret it because our son is almost too tall for it and he is only 3!. Ive seen people get those sit/stand single stroller, which allows the bigger child to stand or sit and the other child to be in a standard stroller seat. I liked the idea of it since my almost 3 year old ( june ) would rather help push his sister than be in the stroller as well. Except when I go on walks to the playground or other planned walks, he really doesnt want to be in it all that much. If I decide to sell my bob, ill message you to see if you are interested because it is a terrific jogging double stroller! Good Luck!
