Hey bod don't worry about the car seat. They've been talking about changing the laws on rear facing car seats for the past 3 years - in Scandanavia, they're compulsory (I think) till age 4. If you are small, you might well have a small baby anyway - DC1 was (is) so diddy that she fitted in her Group 0/0+ till she was 22 months (and even then, could have gone another couple of months), so you may well be able to keep your DC in his/her first car seat for at least 15 months anyway. Remember, it goes on height, not age. (Eyes below top of the seat).
Also, you can get rear facing car seats from 0-3 (i.e. up to age 4) so if the law changes, and you're growing out of it, you just get the next stage up as a rear facer too. So no need to panic.
All you need for the baby for the first 6 weeks is a shit load of babygrows (and vests if its winter), a pram, a car seat and a moses basket. You can get the cot and everything else later when you work out which way is up again. They're simple little souls when they're born unlike now when they're nearly three and demanding a swing with a blue seat
I have lots of girls names if anyone wants some? Clementine, Charlotte, Amelia, Emilia, Amelie, Emma (spot a theme) Sophia, Isabella, Alice (though DH has flatly refused that, because of that slightly obscure song from the 90s "Who the Fk is Alice") Katie, Libbie (though christen Elizabeth). I'm sure there are more but those are my favourites. Not sure we can afford the seven children I'd need to use them all-- Its boys names I'm stuck on. At least I'm not K-Mid - imagine having to pick a boys name that really does work as a King name - not a lot of choice from the British Royal family, is there!!
