Does anyone know that car seat law in Florida. Here in Ohio we have to be in Booster seat till age 8 or until 80lbs. 2 of our daughters will be 8 and 9 so no biggie. Our youngest is 4 and weighs over 40lbs. I am assuming she will still need a booster seat? I swear several years ago children at age 4 did not have to have a booster seat in Florida. Can anyone help clarify Thanks!
