I'm looking for a car seat for my 8 month old DS for when we go to America. He's only small for his age so it needs to be group 0 but I don't want to pay a lot as it will have to go in hold and I'm worried about it being damaged. Ideally if I could one to do group 0 plus it would do as a spare seat to go in nans car once I go back to work. Oh and I want a good safety rating. Any suggestions on where to begin looking? Or am I asking for the impossible by wanting it cheap yet good?
