What is the difference between the original bugaboo bee and the so-called bugaboo bee plus? I bought my bee in Jan 2011; I don't know if it's a 'bugaboo bee plus' but I don't think so. I now want a new canopy (hood) for it but they all seem to be advertised as "bugaboo bee plus" - which I suspect means they may not fit my model. Am I going to be stuck with my old bright pink canopy forever? Any advice?
