I'm 31 weeks pregnant and looking into buying a pushchair / travel system. I have a V reg Polo and have so far only come across 3 that will fit in the boot without having to remove the parcel shelf. I was told in Mamas and Papas that you should not keep a young baby in the car seat for longer than half an hour. This seems a bit strange because if you followed this advice you wouldn't be able to leave the house! In the Mothercare catalogue it says you can keep them in a car seat for up to 2 hours. Which should I believe and can anyone with a small car recommend a decent travel system? Also, is it better fitting a car seat onto a base or strapping it into the car with the seat belt?
