Do Carseats Need To Be Relace After A Car Accident? Is This Only With The Child In The Seat? What If There Was A Ca While The Child Was Not In The Seat...my Dh Wrecked Our Car While I Was Home With The Girls A Few Months Ago And I Just Read That Even In A 5 Mph Crash The Seats Need Replaced....so I Was Wondering If That Only Ment While The Kids Where In The Seats?
