Hi, I'm having twins in October and would like to use DS's old maxi cosi and buy another MC car seat to save money. I really want the option to attach the car seats to a buggy - its so much easier when you're just nipping out and also DS hated going out lying flat in his carry cot when he was tiny. I know they can't stay in car seats for too long but think this will really help me get out of the house even if its just for a half hour stroll. I'd like an inline one if possible as I already have a tandem mountain buggy for when they're a bit older (unfortunately this won't take car seats as its an old model I got 2nd hand. Thanks
