I have a 3yo and 9mo - I think all of the suggestions are great, it really helps to have others perspectives. FWIW - we have the double Mountain Buggy and Maclaren Twin Stroller. I wanted to walk daily so the MB stays up at home and the Maclaren stays in the car. My 3yo walks in fits and starts - her spirit is willing but we do quite big walks so she hops in and out etc. The MB only just squeezes into my boot (Commodore Stationwagon) also and is quite cumbersome but fab to 'drive'. I bought both doubles with the intention of reselling on ebay to recoup some $$ when we were finished as they are both generally in demand. The girls love being side by side and chatting,playing etc. Happy shopping!
