Our daugter was 2 1/2 when our son was born, and she had been king of the rooste, and of the pushcar all that time so I was worried how she was going to take the change. Because her seat is over her brother's and qhite high in comparison, she thought the change was great. The vibe is easy to manuvour, also in and out of busses and metro.
There are a few minuses, which are only noticable because it is so close to perfection, ergo the 5 stars. some minute minusus that I do not think one realy can expect (but if it is something one wants to do often, be aware): when being lifted with children in it, feks. up one or two stairs, it is difficult to find a place to hold on around the frount wheel; its difficult to get into the storage area when a baby is sleeping fully reclined; The big child can not recline for a nap; and finally one can not hang a bag over the handle.
Regardless of these minuses, the most fantastic buggy, and 2 small child solution I can imagine!
