Help, please

[MiauMau]

I'm in a bit bind, or at least I'll be pretty soon. I'm due next month and as we don't own a car, DP and I have decided not to buy a baby car seat and as our friends don't have children so, we can't borrow one
Do any of you lovely ladies know of a local cab company that has them and that can be booked in relatively short notice? We'll need to go from King's to Dulwich Village.
Thanks!

PM me if you'd like ours for free. We were given it by a neighbour and DD has just grown out of it and I was about to freecycle it. It's never been in an accident (but not that much different from using one from a cab firm I guess!). We don't have a car either but it was surprisingly useful.
