Bugaboo Bee. Both my 2.5 year old and my baby love it- I swap them between it and my wrap sling,and 2 yr old walking. They both sleep well in it.
Forward and rear facing, very adjustable and comfy, easy to push, you can stuff a suprising amount of junk in the bottom of it. Handle folds in and out really easily- great for parking in tight spaces. Folds flat. Lightweight. Not for extreme off road, though. But if I could only have one of my prams, this is the one I'd keep.

Have not used car seat as a buggy at all with this baby (number 3) hardly did it with my other two very rarely. I think they are much more comfy in pram or sling, tbh.

I didn't get the baby nest, just the footmuff as I swap between the two DC, and the baby was fine in it- with a bit of extra swaddling.

nappyaddict Is the Mutsy 4 rider light ok for public transport i.e. buses?

I would recommend:

Bugaboo gecko/cameleon - if it's wihin your budget (or Ebay is awash with them) and you're not folding it too often - although the new bee looks FAB and is more affordable.
otherwise
Maclaren Techno classic - as better for folding, and size.

However, haven't checked out all the funky new ones.

Good luck.

Bee is fine from birth.

re flatness, it depends on what you want to use the pram for - i took dd out with us in the evenings, asleep, for say 4 hours, and I wouldnt have liked to have anything there than something completely flat, so they can sleep properly rather than nap. thats just me though.

current health advice is no longer that 2 hours in one stretch in anything that isnt flat up to 6 months. BUT hundreds of children do this and are fine.

They don't have to be 100% flat - 170 degrees is preferable.

Sorry if this question has already been asked on this link but i keep being told that newborns have to lie flat when in a pram etc but the pram i like is the bugaboo Bee which is not 100% flat - the other pram options seem huge and I am living in a city will be managing stairs/ public transort etc.. SO do they need to be 100% flat on their back or am i just working myself up into a frenzy for no reason?

Shiraz - the Ip Op looks lovely - can you tell me where you got it?

I'll easily get a year out of it, though.
Sorry about the split post - eating and typing = hitting buttons at the wrong time.

nappyaddict you're right - my DS is young. And also undersized (!), so maybe I shouldn't rave too much until I've actually used it until he walks...
