Trafficone you seem to have a very strong opinion about this one. I'd be very interested to learn more about the research that shows that car seats cause all these problems - would you be able to provide links? The only research I can find online linking car seats to SIDS are for studies carried out in New Zealand and Quebec - the New Zealand research indicated that in the cases of SIDS in car seats, the parents were also smokers, which was considered a major contributing factor, and in Quebec the researchers said that existing respiratory complaints could not be ruled out. I'd love to read more about the other potential hazards you list.
Obviously none of us want to put our children into unnecessary danger, but I'd be very interested in seeing the scientific evidence before drawing my own conclusions - hence the question above.
To answer your question Octaviapink we've got an inherited moses basket (and yes we're getting a new mattress, before you start having an aneurism, Trafficone) which we plan to use in the house and take when we go visiting. The car seat would be for the car, and when we're out and about. Of course now, with three months to go, I'm envisioning myself strolling around Kew, and taking long walks every day along the canal, but I'm only off work for three months, and i have a niggling suspicion that when it comes down to it, I'll be lucky if I get as far as the corner shop, in which case the carrycot may be an unnecessary expense for something that only gets half a dozen outings in the first 3 months.
We've also got a tiny car, so traveling with baby, pram and other stuff is already going to be a stretch - another reason why a car seat was looking like a good option.
Sunshiney I may follow your example and go with a sling to start with and then move onto the push chair as soon as possible - which push chair did you go for?
