Hi, has anyone heard that not all group 0 car seats are suitable for smaller newborns? I bought a travel system for dd that included the car seat that was described as 'from birth' DD was 6lbs and I felt she didn't look comfortable in it until she was a lot bigger. I was looking around a baby shop today and I spoke to an assistant about the seat I had. She said that seat is only suitable for babies over 7lb. I read all the stuff that came with the seat when we got it and didn't see any mention of this. Shouldn't this be clearly stated on the seat? I'm now expecting my second child and am definitely going to by a new seat.
