I currently have a Silver Cross travel system which I bought second hand 4 years ago. At a guess I’d say it was 6-7 years old. I’m now pregnant again and want to use the car seat with the pram frame for short outings, as I really found this useful first time round - BUT the car seat is out of date and not safe. Any ideas where I can get a replacement? All I can find online is the simplicity car seat, which I don’t think fits my pram frame! Or any suggestions for a good, not too expensive car seat and pram frame I could buy? Many thanks for any suggestions.
