I labored over this question! my son was 2.6 when baby was born, and then we went into winter so i thought a double would be silly, and now that spring is here he is almost 3, and we even got out with it quite a bit this winter- we went for the sit and stand ultralight joovy- it was the most expensive but I wanted the best one if we werent' going to get a double, and it makes a HUGE difference when travelling... I highly, highly recommend it, my nearly 3 year old rides in it all the time and when he is tired or unruly, he sits and I can still strap him in, its perfect and if you have an active 3 year old I think you'll love it!
