We have the mountain buggy terrain (new one) with carry cot on top and note it changes in to a parent facing upright sitting bit for a while. Although dd would t be moving out of carrycot for a while we have been looking around for some form of cosy toes / sleeping bag thing to keep her snuggly in the next stage parent facing bit. I can't seem to find anything online, does anyone know if anything exists or does the normal mountain buggy sleeping bag fit on this way round too?
