Have been looking around at buggies, but feel helplessly confused. There are a few things I have picked up - like making sure it's not too wide (as I live in the city), not too heavy (as I live on the first floor), and that the baby can face me in the beginning. But are there any other killer considerations, or things you'd wished you thought of before you shelled out £400 . Any any recommendations on where to go for good service? I have been in to several Mothercares and one John Lewis, only to scurry away unenlightened after frustrating non-conversations with staff...
