Think I have finally decided on a Jane Powertwin for my DD who will be 23 months when bump arrives, really need some frank advice though. I have a single Mountain Buggy at the moment and love it, would def have a double if it folded up smaller, however the folded size of it makes it impracticle. Given that I love my MB sooooooo much am I going to be really disappointed by the Powertiwn? It does seem so flimsly compared to the MB. Also has anyone got a Powertwin and a Fiesta? Does it fit in the boot? Thanks!!!
