I seen a thread on here the other day but now can't find it.
Is it true you shouldn't (or aren't supposed to) sell a car seat when your done with it?
I bought a travel system complete with isofix base for DD when she was born. I've just bought her a new car seat as she's grown out of the one that came with the travel system and will soon be buying her a new stroller. I'd planned to sell the whole travel system but I read somewhere that your not supposed to sell a car seat. Is this true?
