I have a bugaboo frog that I pruchased years ago in Australia for our first daughter. Does anyone know where I can purchase the adaptors for a car seat and what car seat would be recommended, Maxi Cosi? I want something I can fit to the frame of the bugaboo. I understand the Frog was never sold in Hong Kong and the few shops I have asked said adaptors are available but they dont have them or order them?
