I thought I'd be all organised and start looking around for a wheeled item in which to transport the baby when it arrives. I thought it would be simple. How wrong was I?! Can someone further ahead give me the absolute basic, novice's guide, please? I've already read the MN Best Buy guide but still really don't understand all the technicalities. 
Ideally I'd like to buy one item that will take the baby from birth up to whatever age you stop wheeling them around - I presume this means I need something that will face me to begin with and then face outwards later on when baby is older. What is the inherent difference between a "pushchair", a "lightweight stroller", and a "travel system"? I don't drive so will be doing lots of walking in all weathers plus going on public transport a lot (probably sometimes with a couple of shopping bags). I'm tentatively thinking from what I read on the MN guide that a "lightweight stroller" like the Silver Cross would be better since the one real difference I could understand was that the "travel systems" include a car seat and are much heavier, as well as being several hundred pounds more expensive. But I suspect there may be more to it than that.
