I am pregnant with my first baby & am beginning to think about the minefield that is buying a pram! I want a carrycot style, which the baby can sleep in, so I know it's safe (ventilated sufficiently etc), & the Silver cross Sleep over SEEMS to have what I'm after, but I haven't seen a "real" one yet. I'd be going for the linear chassis & wonder if anyone has one that they can share their experiences - good bad, easy / hard to use etc...
